Just so you know, barely anyone in the real world uses Chromium, and compiling Chromium takes hours (I have done that many times). So that's not an argument. Also, if this is ever becomes a standard or a de-facto standard, it probably will be implemented as a proprietary feature, in the same way as Widevine or more closely SafetyNet -- if anyone can easily get around this, there is no point of doing it.
