Yes, I think this is definitely more clear.  The only one I would change is Op Mode 1-6, Fan Mode = On, Fan Speed = 0, Heat/Cool demand = Met.  I would change the Fan behavior to vendor-defined.   Then for Fan Only mode, I could give Firefly the Off mode they want, but for the other modes, it could stay on at Low, which is what I believe legacy is doing today.

That would be a change in the intent of the DGN.  I'm content to see the new Aux/No Fan mode, as it simply expands the DGN in a way that doesn't affect existing devices.  And everyone should be happy to see any new text that clarifies the existing intent.  But changing the intent of an existing DGN is serious business.  If Firefly wants to change the intent of the existing DGN, then it's on them to make an explicit submission and make their case for the change.
