Maybe it's just a protection against users own lack of knowledge. e.g.
if they see a pulseaudio service and think "hey I use pulseaudio, this
should be enabled" and then enable it, they will suddenly find
themselves switched to pulseaudio system-wide mode (not generally
recommended) rather than pulseaudio per-user mode (recommended).

Just a guess, but I'd personally say that if you are going to ship an
initscript for PA at all (I try to avoid it) then just include it in a
separate sub-package.

Speaking of which... assuming a time when systemd user sessions are the
norm, can a system service conflict with a user service? e.g. say we had
pulseaudio.service active (thus a system-wide instance), it should
really conflict with the user pulseaudio.service... Anyway way to
achieve that? Might be a bit of a strange use case to be honest.
