While I fully agree that we should remove most of this stuff, we are breaking
our API protocol here: We should deprecate these 2 API entries for 1 stable
release and remove it afterwards.

Is there a chance to get the deprecations into the release branch now? It
shouldn't be a problem when Chrome doesn't use it. Otherwise we should perhaps
wait for another release cycle.
