I don't think that's possible. As I said, they are not doing variable
assignments, but processing commands, in sequence. If you do some sort
of auto-combining thing, then the sequence is lost and that's an
If you want to *change* /etc/pulse/default.pa, then copy it and make
your alterations. If you just want to add a few custom things to the
end, then do something like:
load-module my-custom-module ...
Which achieves that level of functionality.

This kind of setup could work for daemon.conf and client.conf as these
are doing simple variable assignments, but it wouldn't work for
default.pa as described above.

Personally I think the reason is more to do with poor integration in
some desktops which I've been trying to solve, but I agree the
documentation needs improvement too (I just expect most users not to
even bother looking! Maybe I'm pessimistic tho'!)
I'll try and incorporate the suggestions here into some kind of update
(i've not read them all yet but certainly will when I get a sec).
