Awesome, didn't know that was a thing
Some light reading

The presence of the two companion Herbig stars complicates things quite a bit, and makes the initial mass of the black hole, and also of the Herbig stars for that matter, a bit harder to ascertain. But yes, I would say that the fact that these stars are still there at all hints that there may not have been a supernova. Black holes and neutron stars have high velocities, because they are ejected unevenly from a supernova event. I am honestly not 100% sure if the companions would be able to stay gravitationally bound after such a violent explosion that launched the remnant out at ~1000s of km/s. I'd have to do the math! Lol.
and here is a quick guide:

Okay, the black hole and the Herbig were some 2,200 LS apart (as is the black hole and the regular Tauri). Wouldn't the black hole accrete material from the Herbig or is its mass too low to have an impact? Would the Herbig's orbit eventually shrink so that it will eventually fall into the hole's event horizon?
The black hole may have hoovered up some of the unbound gas and dust floating around the early system, but unless there was tidal gravity (a possibility since we don't know the initial orbits) or a super novae explosion, the mass of the Herbig star wouldn't necessarily be lost. The gravitational pull doesn't increase just because a star turns into black hole. It only depends on the total mass, and the distance. If anything it might be the other way round. As the initial O star evolved into a giant, some of that mass could fall onto the Herbig (or the T Tauri) star and get absorbed. Thus reducing the mass available to fuel the collapse into a black hole.

Yes, I think it is a misconception that black holes suck up everything just because ... black holes; to quote Phil Plait 
A black hole with the mass of our Sun and in the place of our Sun wouldn't turn the spot into a gaping maw that devours everything and their mother. The gravity will stay the same, only energy radiation will be different, hence no sunlight, no beach partys.
By the way, is there a formula or rule of thumb from which the mass of a black hole's original star can be calculated?

Couple of systems I thought were mildly interesting.
This one is a Herbig Ae/Be main that has 8 large lava worlds, all between 10 and 30 earth masses. The purple planet is also a water giant, not seen one that colour before, followed by a couple of water worlds.
This one has an orange Herbig Ae/Be paired with a black hole, and they're both paired with another black hole and O class. The highlighted planet is a high metal content world over 64 earth masses, gravity of 9.21 and over 64 million atmospheres pressure. The first planet of the row below it is a metal rich world with "only" 41 million atmospheres pressure - but is a balmy 11,071K giving it a 'metallic vapour' atmosphere.
That's just nuts!
5 water worlds and very little else
if only it was 6
I have found six before but I still think your system is better
5 ringed T-Tauris in one system now thats weird lol
Weirdest system I ever came across in my travels was during one of my neutron star farming trips.
That's a Wolf-Rayet N, a Class A Supergiant, and a Class O. The Supergiant was scannable from ~80-100k light-seconds away. Not often that the Class O gets outclassed by all the other stars in a system...
My pet name for the system: The Tribunes. (I thought about calling them "The Politicians", but that seemed too undignified. The point made by the name is the same in either case.)

Really tough one to decide what what to scan. You could spend all day in there. I think I'd just jump out and forget I ever saw it.
Hell, I'd scan all the HMCs and the Gas Giant.. I love systems like that
Some people amaze me with their dedication. I was passing through the Rosetta Nebula the other day and fully fifty percent of the stars in there (I didn't check all that many) where discovered by the same commander who had scanned every planet, every moon and every speck of dust no matter how far away they were from the entry point. The other fifty percent were scanned by one other commander. I don't have what it takes to do that. If it is a really interesting system like the one I found with six water worlds I might scan it all but generally I point myself at the close things and head off.

I'm on the fast train to Beagle Point, so I'm only scanning the things that catch my eyes. Most of those "planets" are very small. I wasn't about to spend an hour or more trying to scan all of that. I left the system ID visible so someone else can have some fun with it.
