In ASDF 3, there is already a function ASDF/FIND-SYSTEM:LOAD-ASD, aka
ASDF::LOAD-ASD, that is being reimplemented by slime-asdf when not present.
I suppose it could be usefully exported from the ASDF/INTERFACE package.
I will leave that to the new maintainer, Robert Goldman.

The ASDF::LOAD-SYSDEF is obsolete. Please use ASDF::LOAD-ASD instead,
at least, if you can afford to use either ASDF3 or SLIME.
