So I was just reminded that I do still have a Xen server that's still
running the 8.99.32 kernel and Xen-4.11. I had not been testing on it
because it still of course has the vnd(4) CHS size bug (and because it's
also hosting my $HOME and /usr/src and I don't want to crash it), and I
had not remembered until just now that I can work around that by simply
padding out the mini-memstick.img file!
And, so....
It works, A-OK, with all other things remaining the same:
# ls -l /dev/xbd0
crw-r----- 1 root operator 0x3a Apr 17 04:31 /dev/xbd0
# newfs /dev/xbd0

So the problem is almost certainly in NetBSD-current itself, and
somewhere in the vast gulf between 8.99.32 (2020-06-09) and 9.99.81
(2021-03-10).
Unfortunately I don't have enough hardware that's Xen-capable and up and
running well enough to allow me to do any brute-force bisecting.
