No mod creators are being banned for "outshining" the vanilla game (seriously, I have not one idea what you are talking about).
You wonder about the quality of the same PC team that created and has updated the game all these years - ok then. We always have and always will take the time we want and need to get things the way we want them before releasing anything. It's been that way on PC since the start - and its more that way on console and mobile now than ever before. Sorry if that doesn't satisfy you, but it isn't changing.
Just to repeat once again:
Re-Logic Dev Team members working on Console: Zero (not counting QA in this obviously, just the folks that "make stuff" like coders and artists and such)
Re-Logic Dev Team members working on TOW: Zero (not counting guidance and feedback, of course)
Both of the above are under Pipeworks.
Core PC Terraria Development is still being done by the same exact folks that did updates for the past several years - at least since 1.3.
***PC Development is not being "slowed down" for this effort on console and mobile, nor for mods, nor for TOW, nor for any other conspiracy theory people want to whip up.
