First of all, thanks for the email.


I agree that supported_keys() is not strictly needed to do the job. But
the same can be told about supported_keys() in media sources: they are
not a must to do the job.

Still, I think it is worth to keep supported_keys() to tell applications
which keys are supported, instead of applications needing to call
continuosly may_resolve() to filter which keys are supported. Actually,
I don't see supported_keys() as a complex function.
