I disagree, sound handling is only essential for audio playback and
production programs, and the later don't and won't use pulse. Programs
feeping and beeping away all the time are an annoyance at best, a
problem at worst.

Gnome isn't Linux, Gnome is primarily a DAU-top. I don't see why gnome
should govern the direction of every distribution. Yes, ubuntu decided
that they want to follow and build on gnome, their release cycle etc.,
but we're not ubuntu.

I hope that adding PA at compile-time won't mean PA will be required.
The piece you miss: PA depends on alsa, it builds on alsa, it can't
replace it. At hardware-near levels there's still alsa at work. If you
use alsa via PA, then you go alsa-PA-alsa.
Btw., last time I checked it was not recommended to program using the PA
API, so unless this changed, developers are still supposed to write
their programs for alsa or whatever else.
