I always remove Pulseaudio because I have never been able to get full
performance in Kdenlive with it running (choppy with AVCHD based files). I have
Jack if I need a mixer, and my small machines (both netbooks and all my Pentium
III /low resource experiments) have video playback issues with pulseaudio using
so much CPU. I've played with Pulse, never been able to get it to cooperate
with these demands.
About "unremovable packages" remember that there is no way to make any package
unremovable to anyone with root/sudo access. The binary can have its
permissions changed to disallow running or simply be deleted, then the package
pinned to prevent reinstallation. In fact, I used to turn Pulseaudio on and off
that way (to stop it from respawning if killed) until I found a volume control
that worked. That was volti, thanks to another contributor on this list. Of
course, someone who understands video editing but not the Linux file system
would be stopped by this if APT won't let you pull the package without ripping
out a lot of other stuff.
Making too many other packages depend on Pulseaudio is a bad idea. Things
focussed on pulseaudio obviously would, but such dependancy on, say, an audio
editor, would have the effect of making that package incompatable with Kdenlive
if AVCHD files are to be used, and with all video players, even Flash, on low
resource boxes.
Not such a big deal with a meta-you can install the meta, then remove it and
anything it brought in you want to remove. Still, that adds complexity that can
stop end users dead in their tracks and for that reason alone should be
avoided. Dedicated machines are just one reason for this, the fact that
everyone's workflow is different is another.
