I suspect that at some point in the very distant past, afsd didn't exit
after mount. Checking the Git history, Debian has been using
start-stop-daemon to start afsd since 2000-11-05, which would correspond
to 1.0.snap20001106-2. I have no idea how afsd worked then. :)
However, start-stop-daemon itself doesn't background anything unless you
tell it to explicitly, and we aren't telling it to. So I think there's
some other problem here; it looks from the original bug report like afsd
itself is exiting before the cache is set up and AFS is mounted.

Yes, probably. At least you probably don't want them attached to a tty or
any of the other bad things that can happen if they don't daemonize.
