Conflicting alternative packages are really nothing out of the ordinary. 
There's quite a few examples additionally to jack:

- wxPython, wxGTK, wxX11
- libav, ffmpeg
- mysql, mariadb

The general guidelines we try to follow is this:

- All conflicting packages mention in the README what they conflict with (i.e. 
jack-audio-connection-kit should mention it conflicts with jack2, and jack2 
should mention it conflicts with jack-audio-connection-kit)
- One of the conflicting packages is picked and placed in REQUIRES, uniquely.
- Everything else is up to the user

Obviously, mistakes/insonsistencies can happen, especially if alternatives are 
introduced to the repo at a later stage. But generally, that's all there is 
and I don't see a particular need to change that for whatever little benefit it 
would provide, but as usual, if the arguments are sound enough, every rule and 
guideline is up for discussion.

Grs,
Heinz
