Yeah, I agree there's no obvious reason why it wouldn't work.  The same reasoning applies here as for D76086 <https://reviews.llvm.org/D76086>:

I.e. once sizeless types are treated as incomplete types (which happens towards the end of the series), we'd have to create a new rule to allow sizeless types only for the pointer case.  But since no-one will hopefully want to throw such a thing, it seemed better to keep it simple and leave the rule unchanged.
