Speaking of variants, is there any interest in migrating one or some
of the existing x86-64 CI jobs to arm64 CI jobs GitHub introduced
recently? I suspect that we won't find any endianness bugs (I
expect they are configured to do little endian just like everybody
else) and there may no longer be lurking unaligned read bugs (but
"git log --grep=unaligned" finds surprising number of them we have
seen and fixed), so the returns may be very small.
Note that we already run arm64 via GitLab's macOS runners. That's not
Linux of course, but I guess that any architectural issues should still
be caught by that.
The more the merrier and it is nice to know we have extra variety
over there.
Not to say that we shouldn't adapt GitHub.
