mixed-text-file allows you to split the string into multiple parts, but
that is essentially the idea, yes.  There are of course other ways of
building it, but it is your task to ensure, that those end up with the
result you want.  In my personal opinion, explicit coding tends to be
best suited to accomplish this.

That should work up to a certain extent – what this basically does is
copy your local default.pa into the Guix store and then
/etc/pulse/default.pa is a symlink to that file in the Guix store. 
Depending on the content of default.pa, that may not actually be what
you want, but unless you're doing very weird things in there, it may
also be a perfectly valid configuration.
Can you check, that /etc/pulse/default.pa is indeed what you want it to
be?  IIRC, you may have to reboot for /etc to change.
