The benefit to put headers files and libraries files into seperated
outputs is to reduce the runtime closure size of packages, for example
my home profile contains xfce, emacs, fonts, etc. has total 5GiB (by
guix size), and they have 300MiB under include.

calculated by:
--8<---------------cut here---------------start------------->8---
x=/gnu/store/0fyhci5kv03rfb9430jqs9wki2ifq5ja-profile
guix size $x
for i in `guix size $x`;
  do [ -e $i/include ] && du -sb $i/include;
done | awk '{ sum += $1 } END { print sum / 1024 / 1024 }'
--8<---------------cut here---------------end--------------->8---

If put headers and other development files into a "dev" output, then
those 300MiB can be saved (won't need to be substituted if substitutes
available).  Note that use a "include" output won't help here if you
leave pkg-config files in "lib", since pkg-config files need reference
its include and binaries need reference its libraries.

So it seems to me a "dev" output is unavoidable, also both Debian and
Alpine Linux use '-dev' packages for the same reason, it should be
familiar to learn..
