Btw, I am in favour of this patch.

>> It both blocks the UBSan patch itself,

Well, I dont think so. ubsan patch works now, right? these folds just makes overhead a bit smaller, right? I would not connect ubsan patch with these folds. We could have ubsan patch in tree and these folds would land a bit later - no problem I think. Or miss I something?
