I think, redhat should have their own root key to sign binary files.
Bootloader of install media can be sign by MS certificates, but only use to add
the redhat root key to UEFI database before install.
It will solve many problems like MS blacklist the keys although redhat said MS
wont do that forever.
And, even you do the all things of A-G, it still wont safe because many
vulnerabilities can let the attacker enter ring0 only use to exploit the exist
signed kernel module or kernel itself.
