Yes, not directly, but indirectly. Giving people the idea that a contentious soft pork pushed through without a URSF it's not only doable, but more likely. To be fair, to BIP110 though, the SegWit soft fork really opened this door and BIP110 methodology is just widening it. Remember, there's literally nothing anyone can do about someone spinning up fake pubkeys. That is a serious validation vulnerability and I don't think there's any (palatable) way to do anything about that.
