That's true, this isn't new at all. but it has been lost for some
times in the audio world in favor of midi, mainly afaik because too
much cables just drives people crazy :)
But actually, implementing it perfectly it jack apps may cost a lot if
your control rate is the same as the audio rate (for example computing
a filter coefs 96000 times per second). I think a new type of 'audio'
port having only a sample per period could be a simple and handy
solution to this (one of the problem may be when you connect more than
one cv to a port, mixing CV isn't necessarily the thing we want to do)
Anyway, CV is still, even after 50 year, a really nice way of
controlling audio parameters, and would be kind of a good solution for
mapping lv2 control ports to jack ports.
