Sure.  Part of the equation here is that (IMO anyway) int128 isn't
sufficiently performance-critical to us to justify putting enormous
amounts of work into trying to make it go on non-mainstream platforms.
It's possible that that could change in future ... but if part of the
cost is notational changes that make it harder and more bug-prone
to use int128 at all, then I daresay int128 will never become that
performance-critical, because it would always remain a niche thing.
