It looks to me that it will be common if you want to reduce closures.
Also, in other distributions you know that you can build-depend on the
-dev(el) package and get what you need without having to know about
various sub-packages (outputs), and the runtime requirements should be
minimal (although there are sometimes problems with unnecessary
dependencies).  As far as I know, Guix doesn't have an easy way to find
what provides particular files to determine the inputs.

I don't think these things are fundamental, obviously, and I may just be
too set in my ways from other systems.  It's all meant as constructive
criticism, of course.
