This is echoed by OS developers and maintainers as well:
Honestly, I'm pretty damn fed up with buggy hardware and completely theoretical attacks that have never actually shown themselves to be used in practice. So I think this time we push back on the hardware people and tell them it's THEIR damn problem, and if they can't even be bothered to say yay-or-nay, we just sit tight.
Because dammit, let's put the onus on where the blame lies, and not just take any random "...." from bad hardware and say "oh, but it might be a problem".
