That is the correct answer.
If that's the case, it is especially frustrating because they supposedly have a 'team' of writers who make an impressive amounts of mistakes for something they are supposedly 'tuned into' (or so they claim).
To be fair, nothing can be done about that (short of erasing Disco from canon), so its moot.
I would hope going forward, that the 4th season will retcon a few things, but this is unlikely... plus the anomaly that threatens all life... meh, it sounds a bit... repetitive (season 2).
Can't Disco s4 focus on rebuilding the UFP and showing us transition to new power sources for a change, exploration of other galaxies and maybe showcasing all those 350 member planets UFP had at its peak?
I don't object to a having a season long arc, but nothing says you cannot tell a good story with sub plots which connect to that.
