As per Dave's advice I've changed the topic.
I posted a fix for this issue to the jack devel mailing list, and I'm
waiting for feedback. It solves these issues for me, so I guess you
could say that it's going to be fixed RSN. After positive feedback it
will be committed.

PS: apparently persistent subtle complaining on high-exposure lists does
pay of on the long run :). Thx to Rui for constantly raising the
priority of this issue. ;)
