Tha hangars make bases less cramped. It does have an effect on balance, but how much is dependent on how fully you normally build up your bases.
All of these can be added mid-game without ill effects, as far as I know.
And what's the point of reporting issues if nobody notices?
I mean, I did the fixes because they were excessively easy and I was already invested in finding out why the mods didn't work, not because I felt any obligation to do so. If the mod authors do their own fixes, all the better. But many don't read this forum here, I think.
