A) a lot of people went to Colonia before there were engineers.
This is not true- it' s chronologically impossible. Engineers were added in the 2.1 release on 25 May 2016. Jaques didn't leave the bubble until early June 2016 and was discovered in the system which became Colonia on 29 June 2016. (The system wasn't formally renamed Colonia until 25 October 2016). You literally couldn't go to Colonia pre-engineers because it didn't exist. [1]
The majority of early activity around Jaques involved hauling first meta-alloys and then other supplies up from the bubble to get the station back to an operational state - with many of the several thousand people involved in this making multiple runs - with this continuing to mid-August 2016.
From December 2016 to May 2017 there was also the Colonia Expansion Initiative series of CG, which again involved repeated round trips from the bubble to Colonia and back to establish surface bases in the region.
Pretty much the first half of Colonia's history could be summarised as "a lot of trips back to the bubble to pick up more stuff".
They have deliberately caused unnecessary grief for people.
"People" might be overstating the case here. "A person" might be more plausible, though I suspect there are
zero people actually affected by this.
Literally the only way you could be affected by this is if:
- you didn't unlock the really easy engineers in the month before Jaques was discovered.
- you went out there immediately on hearing the news
- you've cared so little about engineering (and Guardians, the T-10, the Chieftain, most Tech Broker unlocks, Thargoids, or any of the other bubble-exclusive things) that you haven't been back to the bubble at any point in the last
two years
- you now suddenly have an urgent need for some G1 blueprints on your ships. But just G1, not the G5 you'd need to return to the bubble for anyway.
- you think a 44kLY round trip is a really long way (but were willing to rush out 22kLY
pre-neutrons in an unengineered ship to see Jaques)
Generally there is a subset of players who doesn't unlock engineers (or maybe just one of Farseer or Martuuk for the G5 FSD) - the dedicated explorer who spends as little time in inhabited space as possible. They, however, are really not that bothered by a 44kLY round trip because travelling large distances is what they enjoy in the game. Putting things a long way away is not "grief" for them any more than putting weapons on NPCs is "grief" for a bounty hunter.
[1] You could go to the Eol Prou nebula, of course - but I think one of the reasons Frontier picked it for Jaques to land in was because people hadn't: the initial rescue teams found that basically none of the systems, even the interesting ones, had any discovery tags on them.
