OK. But doesn't asdf-output-translations (the replacement for
asdf-binary-locations) by default redirect the output to a user cache?
Or did you disable that?
Do you want me to merge that into upstream ASDF with #+abcl conditions?
Note: If ABCL supports matching and translating such paths,
there could be ASDF-Output-Translation rules by default with ABCL
in the idea of
(#p"/**/*.jar/**/*.*" (:home #p"**/*.jar/**/*.*")

How do you propose to do that?

Juanjo of ECL was thinking of a different delivery mechanism, where
compiling a ASDF system would yield another ASDF system of the same
interchangeable name, but the content of which would be just one or
several binary objects to load.
Perhaps that's what you really want to be using?
