… and that is not a problem for the XML version, because the string is being used instead of the value.  (But then if two enumerations share a string, you have the equivalent problem in the XML serialization.)

Anyway, I haven’t seen a piece of real-world YANG that actually has this problem, so I would be a bit reluctant to make CBOR-based implementations more complex (and less efficient) so solve this (non-?)problem.
