This has ALL the flags of a patch that must not be merged to a stable branch:
- It is rushed.
- It is badly designed.
- It affects a central piece of code.
- It is invasive.
- It has no proper tests, and affects a piece of code without proper tests.
- It comes not only after the freeze, but even after the release.
Except for one:
- It does not change the source and binary interfaces.
Merging that code is making a joke of the release process, a joke of
developers who abide by code freeze, and a joke of the hundres of millions of
users who don't care for (or already gave up on) Chromecast support.
As if it was not bad enough, there is no credible plan for ongoing support
here. Because of the current state and nature of the modified component, the
- We will not be able to attribute bugs to this patch or to whatever else. So
we will not know whether to revert or not.
- We will also not be able to backport fixes because they are also impossible
to test, and the code base will drift too much too soon anyway.
3.0 backports shall be contained to their own code scope. Applies for
Chromecast, as to anything else.
