Good idea.

Drivera are definitively a lot different between  jack1 and jack2  
and  internal clients a bit (a new "jack_internal_initialize"  
function to be used when internal clients are loaded using the new  
jack2 control API (or jackdbus))

So I don't see too much how they could *not* stay separated....
