Why should a system architect cater for large ships. Pre-colonisation there were plenty of systems that only contained outposts
Also, who knows what will happen in the future, e.g. with Vanguards
Aside from it being in their Best Interests to do so you mean.
In reality, if a Faction, and/or Military Power, wants to Maintain a Territory, even if only to serve as an Enclave way-stop between Major Locations, what do they need?
They have to ensure that anything that they Build in the Middle can support itself to a degree.
They have to ensure that if things go south, that they can hold out long enough for backup to arrive.
They have to ensure that they can Repair Vessels that may be passing by, and possibly Refuel them.
They have to have at least enough of a Functioning Economy to be able to Justify Operating Costs.
Let's think of a Massive Country for a minute, something like America, China, or Australia.
If I wanted to get from one City on one side of the Country, to another City on the opposite side of the same Country, why am I not Travelling in a Strait Line?
Firstly, there is the Roads, there just isn't one Strait Ultra Long Road.
OK, same as how System Stars are not just in one Massive Strait Line.
Then there is the issue of Refuelling, either the Transportation Vehicle, or just oneself (Eventually, you're going to need to take a leek, eat and sleep).
OK, one can argue that you're in a Star Ship, but I'd argue that your Ship will still need Repairs, Maintenance, and Stop to pick up Food and Water, and empty the Bog.
Then there is the Terrain, particularly in Australia, the Terrain is not friendly to Tires, and other parts of the Trucks going across it.
Some System Stars burn much Hotter than others, so, will do more Damage to Equipment as you go by them, same principle, just in Space.
Let's take a break to look at the Panama Cannel.
It's an astonishing feat of engineering, right.
OK, now let's say that they only Built it to handle Small Ships, anything that was 'too big' to fit, would have to take the long way around.
This would then mean that entire Supply Chains would either Collapse, or just not be viable in the first place.
OK, so what pays for the Continued Operation of the Panama Cannel?
Those same Larger Vessels that would have never otherwise have been able to go through it, if they hadn't have provided the infrastructure to support them.
.
OK, so what could this mean for Vanguards?
OK, let's look at what it could mean...
Just by the Name, a Vanguard, given the Context of this Game:
"The foremost part of an advancing army or naval force." (Definition 2 listed on Oxford Languages)
So what does this mean?
We could expect another Conflict to arrive on our doorsteps.
A Prelude to yet another Thargoid War maybe, we have been seeing more of those things of late in recent weeks.
Something other than Thargoids?
OK, so, what about all of these Outposts?
OK, so let's say you've placed a Coriolis out from one of these tendrils of Outposts, and you think it's going to be fine.
Let's assume that every single Outpost between you can your Coriolis has just fallen, now what?
You have a Coriolis that is now struggling, OK, it needs Water, it needs Food, where is it getting that from?
Oh, the nearest Location that it can get these things is 200 LY away, OK, you can Jump your Ship over that right?
Wrong, there's an entire Army of something between the Supply Base and the Coriolis you only finished Building last week.
OK, what about Fleet Carriers?
Let's assume for a minute, that there is some problem which maybe is preventing them from making Jumps over these Regions.
Maybe these Mega-Jumps attract the Enemy Ships, and thus, a 200 LY Jump is out of the Picture.
In short, that Coriolis in the middle of nowhere is basically done for.
Congratulations, you've left them out there to die.
However, let's say it's not your Coriolis, you're just the person who placed 100 Outposts between you and that Coriolis.
Not your Problem? Maybe.
Is it your Fault? Yes
Your Actions now, can affect whether or not the Later Updates and DLC's are going to be Fun OR a Nightmare.

Just about anyone who owns an Electric Car will know the pain of not having anywhere to Park.
Sure, you can bring your own Solar Panels, and try to Charge your Car with those, but who does that really?
If you can't Park anywhere, you're not likely to make the Trip unless you can make it one, right?
