But you don't "just get plug and play" with MIDI.  It's all about
learning with MIDI.

At the very least with OSC you need to have a (dynamically changeable)
path prefix for everything (eg such a defined "profile" would definitely
have to allow for an undefined prefix portion), so no matter how you
slice it you end up needing some sort of "learn"-ish system anyway.  So
even with such profiles the real problem to be solved is still service
discovery and namespace enumeration (eg back to square one).
