I've full access to all engineers and I've been using them extensively on every new ship I buy. I've also been to colonia in the past, and spent about 3 months there, visited BP and finally returned to the bubble.
I mean to say that this change doesn't affect me, personally. Having said that, I think it's stupid to ask people in Colonia, those that haven't used engineers before to travel all this distance and back. If they don't, suddenly they're at a disadvantage against all those that arrive fully prepared and able to engineer the ships they buy locally without having to wait 60 hours for them to transfer from the bubble and at a huge cost.
Why does this company have to give with one hand and take with the other?
Thinking about it, this could be an opportunity. If they remove the low level unlock requirements in Colonia , which I suspect they will after this thread and community feedback then with some extra work they could add some extra cool gameplay.
Namely if you are a starting player in the bubble and you have not unlocked the engineers in the bubble then you can, instead of collecting all the materials in the bubble, then fly 22k ly instead and have an adventure with a fun reward at the end. Alternate progression paths are always good.
