That seems pretty unlikely to me, but even if it does happen, it's
just a bug which we could simply fix when we find it. I mean, I don't
want to have bugs, but there's no patch that is free of all risk. If
we go through and look around at how this is handled in various
places, and check as carefully as we can for possible problems, I
don't think it would be a particularly high-risk patch.

That seems clear, but trying to be consistent about the types we use
for things is a good idea on general principle, even if we have no
intention of doing anything that really relies on it any time in the
forseeable future. If nothing else, it might avoid some compiler
warnings.
