Sure.

Forgive me, as it's been quite some time since I initially tested this. I
believe during testing with the current default xsession managers will create it
but xwayland sessions will not. Given that systemd has determined they need to
ship this as a global tmpfiles.d entry I assume there is more nuance to this
than what I have outlined.
