Indeed, it was working fine as an initial step to get the ball rolling and
the spec adopted, but having to generate and reference an
intermediate, temporary asset is not great and has drawbacks. Now
that the spec is live and proven in production in Fedora 36 it seemed
to me like a good time to introduce a first-class option, to make further
usage and adoption as trivial as it can be.
