Anything that differs?
As a reader of just the comment I wonder why it is needed, hopefully this can be improved on to help other readers understand it. Maybe: "Mostly identical to YX1FSF but different identification"

The hard part with explaining why the model is different is because the parts of the protocol that are identified and named in the code remain the same for this model. The only differences are that this particular remote has a different set of static "unknowns" than the other models, along with the addition of the ModelA bit needing to be set like the YAW1F remote.

I don't know if it adds benefit to explain that the model is "Similiar to YX1FSF, except for different unknowns". Seems it would add more confusion than clarity?

How about "same as YAW1F, model bits differs"

Indentation seems of YX1F8F section should have identation of 2 spaces, not 4?

Should unknown comments be updated to reflect the remote model, maybe with reference like See stateReset or similar?

I agree that I think this can be a more useful comment. Perhaps all the comments for unknowns should be updated to something like "Value depends on remote model, see stateReset".

Thinking ahead I could potentially see listing the model names on the comments becoming a tedious list to maintain in a comment, so I don't think we should list the initial values for the respective models in the comment. This would only be an issue if more models were supported that required different values here though,

Yes I'm thinking // remote model bits, see stateReset on all of them.
