That is nice, but is still a bit more demanding from users:

1. They need to know how to compose multiple G-Exps expressions such as
mixed-text-file and file-append.
2. They need to know to use ".include" directives from PulseAudio.

My proposed change reduces the knowledge needed to just a single usage
of a G-Exp file-like object, such as plain-file or local-file; I think
that's a bit easier to grok for starters.  The resulting configuration
is also easy to inspect; it's all under /etc/pulse as the user would
expect.

Thanks,

Maxim
