I'm honestly curious as I don't actually have any reference. Also as far as item 3 isn't hard for it to be a "user-visible" regression if there are no users outside of the vendor that is maintaining the driver to report it? Again I am assuming that the same rules wouldn't necessarily apply in the vendor/consumer being one entity case. Also from my past experience the community doesn't give a damn about 1. It is only if 3 is being reported by actual users that somebody would care. The fact is if vendors held that much power they would have run roughshod over the community long ago as I know there are vendors who love to provide one-off projects outside of the kernel and usually have to work to get things into the upstream later and no amount of complaining about "the users" will get their code accepted. The users may complain but it is the vendors fault for that so the community doesn't have to take action.
