I forgot about that. Perhaps it would work to assume that everything before the 
first slash is the base system. 
Thus:
$ guix provides --asdf-system xxx/a
sbcl-xxx
ecl-xxx
cl-xxx

Also for completeness: guix package with asdf-build-system and no #:asd-systems 
get the system name from the package-name. I have already accounted for this.
