"guix shell" is for making packages available in the environment. 
Currently, "guix shell -- foobar" does not make any packages available 
-- it's effectively a no-op except for setting GUIX_ENVIRONMENT. As 
such, I expect nobody is actually relying on "guix shell -- foobar" to 
not load guix.scm or manifest.scm and I think that if we go for this 
change, the migration timeline can be rather minimal.
