I have not checked the docs yet, but from what I read so far the protocol is actually easier, with clearer fixed size messages for usual operations, with much more information.

But it is always required MIDI 1.0 compatibility, so if your device need the extra bits, it activate the MIDI 2.0 protocol. IIRC it is possible to use other parts of the MIDI 2.0 as MIDI CI with the old MIDI protocol.

Also things like MPE I think are really improved, as current MPE is an ugly hack using channels. Time wise MIDI 2.0 should be easier to implement than MPE, IMHO.

The most difficult part would be the MIDI CI (Capability Inquiry) to first set up the MIDI 2.0 protocol, and then to send information about current device. But the info about the current device is actually a JSON file, so not really difficult.
