can you mark all the changes that should be reverted when material design is
default as such? Some of these are not obvious. (The obvious ones like
MaterialDesignController::InitializeMode() don't need explicit docs)

Will do. MDC::Initialize might not go away, at least initially because it caches
hybrid mode.

Done.
