OK, again, if this is required, why don't we ENFORCE it?

It would be trivial to bind a special variable around the body of
LOAD-ASD, and put something in DEFSYSTEM that will raise an INTELLIGIBLE
error if that variable is not so bound

(error "Do not load an ASDF system definition outside of ASDF:LOAD-ASD")

Otherwise, we are just encouraging programmers to shoot themselves in
the foot.

I will put in place such a check.
