I doubt if anything has changed on this front, but this type of
specification was ruled out of scope for EME. EME uses the term and concept
"CDM" only in a notional manner, and does not specify any concrete
interface to such a component.

It is likely that interface and any mechanism for adding/extending UA
supplied CDMs will remain UA specific, that is, until some organization
steps forward to standardize it (assuming UA vendors are willing to do
that... a dubitable proposition).
