So MCUs or any embedded that doesn't get updates will likely only be good for up to the validity of the included CA root before bricking up?

These days thats up to 15 years. Talk about programmed obsolescence.

I think there's a real argument for trying to push "user must be able to control their device's trust anchors" as the next right to repair battle.

If you don't, you can never tell what a device is sending/receiving, and devices have a hardcoded end-of-life date where they become useless. Would love to see groups starting to push in this direction.
