Is it part of the nature of the DRM technology that it can't be walled off in an XPI? I find myself thinking the change would be significantly more palatable for those who care deeply about the division of open and closed source if Mozilla could implement this by building a video-supporting XPI that users can choose to not install (thereby verifying that no closed-source blobs are living in their browser, spying on them or whatever closed-source blobs do that is so undesirable).
