They have. Hair clipping they don't seem to care so much about. When equipment clips, they are more likely to do something. I don't know why it is, but it is.

They changed the label on the spring shirt from a short shirt to a long one, and thus sashes and such then disappeared on pants when equipped together with the spring shirt. People liked the shirt because it was one of the few that didn't alter bottoms. They didn't explain why they did that to the spring shirt, but it was probably clipping. I had seen it clip into one pair of bottoms, and the entire point of removing belts/sashes/skirts(and now butts) on what's considered "long" shirts is to avoid clipping.
They've also disabled rings on 2B's gloves. I just remembered my friend telling those clipped into something. Perhaps to fix the clipping, the rings had to go for some reason? I don't know, but no cares about talking about that because its not about butts.
