That is my experience too. Once jack is started and the
pulse-jack-bridge runs, all audio-trouble is gone. Any sane
audio-application supports either Jack or PA automatically. And I cannot
see, that the PA-bridge increases the rate of xruns(as of now I have
zero of them while experimenting with Guitarix and Qtractor and watching
YT-videos as well (*videos *with* audio that is...).

It should be easier to disable PA to a near-removed status though....

Not sure, if that works soo good for every good thing can be improved
and should be ;-) but regarding video: anyone, who edits a video that
shall be used at least semi-commercial, does professional video work.

If we talk about Cinema-Movies or professional TV-Shows, we do not talk
about normal PC anymore. Even the cheaper TV-shows are still produced on
dedicated workstations, let alone Films. Anything beyond that such as
video for the web can be done and is done in Linux for years now. Have a
look at the Blender-Movies, if you really believe, only vacation-reels
can be made in Linux.

Ahh yeah: and these workstations usually run Linux too...
