That would be counter-productive. You statement is also not correct.
jack clients can correctly compensate for latency, and also do that in
situations when no audio hardware is involved.

The fact that not all jack clients do this is not reason to constrain
others.

Only MacOS/X offers an interface to query systemic latency from hardware
interfaces.

If you don't need to do inter-application routing, I would highly
recommend against using JACK only to abstract a single audio interface.

A user asking for ambiguous latency situations is not an design issue
with JACK. The 'range' was specifically added to account for this and
allow jack-clients to cope with it.
