Well, that’s not what this comment in g10/homedir.c appears to say:
/* It has been suggested to first check XDG_RUNTIME_DIR envvar.
* However, the specs state that the lifetime of the directory MUST
* be bound to the user being logged in. Now GnuPG may also be run
* as a background process with no (desktop) user logged in. Thus
* we better don't do that. */
So, either we *want* a directory that gets removed when the user logs
out, and in that case we should probably use XDG_RUNTIME_DIR (if it is
set) instead of hard-coding /run/user/$UID, or we do *not* want to use a
directory that gets removed, and in that case I believe it would be
better to make sure we do not end up accidentally using such a directory
(when XDG_RUNTIME_DIR == /run/user/$UID).
