This part wasn't directly addressed, so I'll answer it. Because it does give a bit of an insight into the doctrine that "the FSS has dumbed down exploration".
You couldn't directly see if a planet was terraformable in the System Map after the honk; it would just say "Unexplored". But terraformable planets only show up within the "Goldilocks zone" of a star. You could use a third-party tool to calculate the Goldilocks Zone for you, or you could simply guesstimate it by personal experience (eg. "this is a G class star, about the same as Sol, so the GZ will be about the same as Sol's: 450-700 Ls"). Using the "old ADS way", on the post-honk system map, you could get distances to all objects, so you could see at-a-glance which objects were likely to be "in the zone" and which were not; you'd then fly out to the suspected terraformables to scan them and see if you were right or not. And because of some quirks of the Stellar Forge, you never really knew if you were right or not, until you flew up and scanned. An experienced explorer could "get it right " maybe 90-95% of the time.
Using the "new what are you doing way", you cannot know how far away a possibly-terraformable is, until you scan it with the FSS. Yes, it does pop up a distance measurement in the FSS right before you actually scan it, but you have to go to the trouble of finding it and tuning it, so you may as well take that last half-second to zoom in and scan it anyway. So if it's terraformable-hunting you're after, you need to scan every single HMC, Waterworld, Rocky and Metal-Rich planet, just on the off-chance that they're terraformable.
So, finding with certainty the terraformables is quicker with the FSS, but it removes the element of skill and luck it used to have, and also eliminates the ability to see at-a-glance that a system definitely contains no terraformables. Actually scanning the terraformables is quicker, since you don't need to fly all over the place. You can then decide to Map them or not.
Another "complaint" I've heard that's ancillary to the FSS debate: FD finally gave us an Orrery View system map option, at the same time as they removed one of the primary reasons people were asking for an Orrery View: so we could easily plot an efficient route to scan the bodies of interest in a system.
