Rolling back this patch would be a fine start.
They aren't going to do that. There's no documented indication that this patch created more problems than it fixed. Yes it created problems. The people that see problems are showing up on these boards to point them out.
However, it also fixed a lot of problems. Those people are not all showing up here to tell us about that though. Steam is an easy platform to roll-back a patch with. If Bethesda really thought they had done more harm than good, they wouldn't even have to do anything, just ask Steam to roll-back the updated version. They haven't done that, though, so I think we can assume that the patch, crazy as it sounds, is a net positive.
Furthermore, I imagine that they plan to build on what this patch has done anyway, so if they roll back, they'll just have to roll forward again anyway when the next one comes out.
