So far, I haven't seen anyone step forward saying that they intend to
produce a pluggable CDM if browsers were to provide an integration

On the other hand, there's no indication from browser vendors that
also have DRM back ends in-house (Google, Microsoft, Apple) whether
they'd provide support for pluggable CDMs in their browsers (as
opposed to only integrating their in-house DRM without a public API).

Considering what's been said so far, pluggable CDMs might be a
theoretical thing that no one intends to produce.

Indeed, which makes me wonder why previous messages in threads on this
topic have implied the integration of pluggable CDMs would be simpler
than the integration of NPAPI plug-ins.

It would seem healthier to the Web to propose a non-proprietary,
non-encumbered CDM from the start instead of opening the door to
proprietary and encumbered CDMs.

A non-encumbered CDM emerging later might help new Web sites later but
it won't help browsers if by that time there's enough popular legacy
sites that depend on encumbered CDMs.
