My thinking was that skipping such cases would make things less consistent, but I don't mind skipping them if you prefer a more pragmatic approach. I don't have any more such cases in my queue, remaining changes that are more practical.

No, I think it's probably fine to do; I agree that it's good to go through the code to catch cases like this, to make them consistent.

I'm trying to feel how one would be using wrap on arm64x and what the logical behaviour would be. Practically, doing it for both sides feels most logical. I think it's possible that one could want to do it for only one side though, but it'd be messy to express this (so if one wants to do that, it's possible that one would need to supply suitable dummy symbols for the other side).

So I think it's fine to merge this!
