I aborted, since I realised that guix package -s doesn't include the
source url and hash, which would be important for a testsuite...

Some interesting measurements:
guix package --list-available | grep -o --regex "^[a-zA-Z0-9-]*" | wc -l
3797

cat guix-metadata.txt | grep --regex "^name: .*$" | wc -l
13949

looks like we have many package variants?

and an example of what guix package -s guix exports
