I don't claim ownership of anything, but I would like to be notified
of PRs opened against the following paths where I've put a lot of
work into cleanup and deduplication:
lib/systems
pkgs/stdenv
pkgs/build-support/cc-wrapper
pkgs/development/compilers/gcc
Apparently CODEOWNERS is how you tell github you want to be notified
of such things.
