Ok, my fault, when I was researching on this subject some time ago, I
found that these extension where disabled by default by the upstream
(generic reasons like "obsolete" a/o "insecure") in favor of the new
XACE extensions (which seems to be at least not used/incomplete, maybe
someone has more updated infos?)
After that various distro (debian, red-hat, ..) have re-enabled it, eg:
but i'm on Slackware (and Alpine) so I didn't noticed it :)

That's interesting, good to know; I was also using ssh -X a lot, but
since it was disabled upstream I got this kind of troubles all the times
I tried; probabily I have to test again, using the same distro/settings
on both clients and server.

Did you already tried to recompile xorg on alpine with -xcsecurity enabled?
