If so, then e.g. pipewire can be started as dinit user process/service, correct? Currently it seems to be started from desktop-session startup still, which seems the old way. Or I am still misunderstanding…
That is correct, you can create a pipewire user service in /etc/dinit.d/user/pipewire or ~/.dinit.d/pipewire & enable it with the dinitctl enable commands as your own user
It is correct that antiX has kept the desktop-session way of doing things by default.
