The way it should work is that during the OS install the OS can ask to have a cert added to the keystore at which point UEFI pops up a screen that says something like:
This would at least be a vendor agnostic way of enrolling certificates instead of the MS certificate just always being pre-installed. It should also of course be publicly documented exactly how the process works so everyone can use it.
Universal Blue distros do that. For some reason you need to enter a password though.
Problem being, of course, that you can add more certificates, but you can't revoke the original M$ one. And since it's vulnerable and you can't get rid, then these exploits still work and there's nothing you can do to stop it.
Computers shouldn't come with Microsoft keys preinstalled to begin with (or an operating system for that matter). Microsoft being able to have Windows preinstalled on the vast majority of non-Apple PCs is how they gained their monopoly in the first place.
You should be able to remove any or all the certs as well, although I could see an argument for requiring you to enter the BIOS to do that.
