It does not do that, or more exactly it does even more. My
understanding is that the existing implementations use
"ssh-rsa-cert-v01@openssh.com" name not the "ssh-rsa-cert" name.

If we are just documenting the existing protocol, we should just do
that and keep the @openssh.com namespace intact so we do get
interoperability with the existing implementations. If we are defining
new format "ssh-rsa-cert" then the specification should be open for
modifications and discussion whether it is needed or not.

My proposal is to just do the first thing, i.e., document the existing
"ssh-rsa-cert-v01@openssh.com" format and keep those names.
