I suppose, but then calling FORMATTED-VERSION would just amount to
memoizing the value of FORMATTED-VERSION into a slot on the ASDF system
object. Why would that be a win over just calling FORMATTED-VERSION on
I.e., we could just provide something like
(defgeneric FORMATTED-VERSION (C &optional version)
(:method ((COMPONENT C) &optional version)
(or version (component-version c)))
and then the programmer could extend this as needed.
