With all due respect, you can't claim to speak for the entire kernel
and FLOSS community of users and developers.

The feature is optional: it does not enforce additional constraints on
users, but exposes additional functionality already present in
hardware, for those who wish to opt in to it. Those who wish to avoid
it can do so, by simply not making active use of it.

Cheers,
Daniel
