That's been my experience. I haven't used jack2 much, but when I tried it,
the jack1-compiled stuff I tested all worked fine without a recompile.

There are only 2 builds that list jack2 as a requirement: MuseScore
and lives. I just built & ran lives with jack1 and it at least compiles
and runs (it's a video editor; I didn't actually try to edit any video
with it). Actually, lives offers several choices for audio playback,
including both jack and pulseaudio. Seems like jack should be optional,
not a required dependency, but the maintainer might have a good reason
for doing it the way it's done...

MuseScore requires qt5-webkit, which I didn't already have installed,
so it's going to take a while to build. I'll try it with jack1 also,
and get back to you.
