It can't be overstated *how* trivial it is. I've found that users of
mutable-state package managers just don't believe me when I tell them.
It's even easy to have out-of-tree packages, pulled in with
GUIX_PACKAGE_PATH, that depend on in-tree packages or package updates
that you haven't upstreamed yet.
