How exactly is FDev failing to deliver on their promises? A single player can colonize one or multiple systems – it's definitely feasible. In our squadron, everyone is doing it, each on their own, and many have already created chains to reach certain (fairly close) systems solo. Imagine what a squadron, even a small one, can achieve if they coordinate and focus on one system at a time.
You can already colonize with your faction since it automatically enters the system even if you colonize from the other side of the bubble. So, I don't understand where the problem lies. Do you want to bring it under control? Do some BGS work on that system. After all, it's a system with very low population and only four factions, so you can reach control very quickly. Even a single player could do it in a week and a half.
What's the point of wanting to go 832 LY away without anyone around? Just so you can have your little systems unassailable via BGS? And I bet you'd want the colonizing faction to be unremovable from system control. I'm sorry, but it can't work that way. A system is a system, and just as 'vanilla' systems can be invaded and controlled by different factions, colonized systems cannot escape these logics. It would be terrible for BGS mechanics.
Oh, and one more thing to consider: do you really think other player factions will be interested in your colonized systems, especially if you manage to get that far? The entire BGS framework will have to be revised following this update, or at least squadrons will revise many of their BGS policies. I'm a BGS player, and personally, I have no interest in conquering small player systems or managing systems where a casual player has brought my faction as a colonizer. For me, those systems are useless, and my faction can go into retreat for all I care.
So, really, I don't understand what the core problem is.
