Simpler, yes. More compatible, not much. The only cases that I can see
the proposed syntax would break are socket paths that

 * start with "[" (ie. they are relative paths, which don't make any
sense anyway, I think) or
 * contain commas.

Well, the simplicity point is valid. But if the user wants to set the
server manually, completely separate server strings for different
pulseaudio protocols require him to always specify hosts twice, which is
annoying and a bit error prone. Based on very little empirical data, I
would guess that the most common case for manual server configuration is
when just the server hostname is needed. I would like this to still
work:

$ PULSE_SERVER=gurki pavucontrol

(Ok, that would still work, because pavucontrol doesn't currently use
D-Bus, but you get the idea.)
