It seems like a regression to me and it's not helping people who want to
use both pulseaudio and jack together.

For most professionals it's completely unnecessary to remove pulse as jack
can run on a second "pro" soundcard. This issue is only a headache when
the user has only one sound card to work with and given that is the
majority of n00b or amateur users it makes sense for pulse and jack to
work well together.
