Hello,

/var/run typically is a symlink to /run. Are per-user
subdirectories of /run common practise on other ditributions nowadays?
(I only know that Debian does not have them.) Having a default that
would not work for most of the users is probably not desirable.

You could use (a subdirectory of) /tmp.
