Yes. It leaks memory and can get stuck on some error conditions, but
it's definitely about as simple as you can get.

How so? I can see how it imposes a little challenge for cases where
synchronous operations would be good enough, but I consider the
asynchronous operations to be mainly a good thing for interactivity (the
ui doesn't get stuck waiting for reply from the Pulseaudio daemon).

I don't know, I wasn't around when pacmd and its protocol was written.
For what it's worth, I'd like to get rid of pacmd and its protocol.
