No concrete plan yet.  A remote possibility might be to indeed rely more
on gexps and maybe get rid of input labels, like:

  (define foo
    (package
      ;; ...
      (inputs (list guile-2.0 gtk+ (gexp-input glib "bin")))))

but this introduces other challenges in particular wrt. package
customizations.  So, we’ll see.

However, for new APIs, I find it usually better to use the above gexp
style rather than the current package-input style.
