Isn't there something that says if the OCPD is indicated on an appliance it must be installed per that?

Example a dedicated circuit to a hard wired washer that indicates 240v 15 amp OCPD on the name plate.

Would an existing 2p 20 amp breaker need to be changed out to a 2p 15 amp in this instance even though the wire is #12 ?

If it merely says current=15 amps I would say no. If it says something like use a 15 amp OCPD then the 20 needs to be changed.
 
Not sure if this means MAX circuit breaker or not. That first column is showing a 10 amp breaker. That is not a standard size, so to me that makes this table a suggestion and not a requirement. The overcurrent rules in 422.11(E) probably apply. If the above info marked on the appliance or in the manual?

10amp was added in 2023 edition? Or was this just a proposal I heard about?

It's on both.

I usually don't sweat the small stuff but this caught my interest.

I was wondering if when this is indicated on the nameplate if they're using the BCOPD as a means of protection for the unit somehow.

Not sure.

It would really suck to have to add a 10A fusible disconnect for that. 10A may be a new standard size, and some manufacturers offer 10A breakers in single pole (I've see some from I think CH and QO), but they seem rare. TO me, a manufacturer should list something for use on a 20A protected circuit, as a normal cord and plug item could always end up on a 20A circuit.

To me a 10amp breaker is a waste of good space.

I’m sure there’s uses for it and especially more in the future but for now I just don’t see it.

This is pretty hard to read do you have a link to the specifications?
