True. I did not want another machine variant which enables these. Maybe
MACHINE_FEATURE like "tf-a", which then for genericarm64 adds these
qemuarm64 configs. Using other custom variables doesn't feel right either.

These do not impact anything in systemd-boot, kernel or userspace
or in the wic image which is compatible with a lot of HW.
