I would be interested to know how a W3C specification could require an
implementer of an implementation detail of EME (i.e., a CDM) to register
it, or to put it another way, how could the W3C enforce such a requirement
even if it were written into the spec?

The only type of registry I see as practically implementable would be
strictly voluntary and have a primary purpose of collision avoidance among
key system names.
