One aspect of the proposal which has not yet been discussed is that it would allow browsers to expose to users information about which content protection mechanisms were being used by which sites and to enable users to disable those mechanisms if they chose. Those options are not available whilst content protection is buried in plugins.

A user who wished to review the source code of any software to be run on their system could simple disable all CDMs for which source code was not available.
