I didn't arrive at trying :pin gnu from anything in the Internet, but from
reading the use-package documentation (just this time ;-) )

My feeling is that if I set package-install-upgrade-built-in to t and pin
a package to (say) gnu elpa, that should be enough. I may resort to
use-package from everything, but would not use :pin on built-in packages
that I don't want to upgrade (makes no sense, right?).

It's a bit like adding a load-path to the use-package call
and download the package externally
(for example cloning with git) into that directory, which is
the way I use to get the development version of, for example, org-mode
when I want to contribute to it.

Does it sound strange?
