This is not how things are supposed work on Linux. Libraries should
only link against libraries from which they use symbol. In
pulseaudio's case that's just libpulse, because that is our public
API. Overlinking is generally frowned upon.

Indeed, this is one of the reasons.

Couldn't you just add Libs.private when compiling pulse applications?
