Sorry for the delayed response;  I don't think that has to be expected.
While use-package can utilise package.el for package management, my
impression is that it is at liberty to be more flexible/declarative.

I have tried it out myself, and it doesn't appear to do anything.  The
issue looks like that `package-installed-p' doesn't respect
package-install-upgrade-built-in or :pin.

IIUC the feature would be that if a use-package form has a

     :pin gnu

argument, then this is an indication that we want to install the package
from GNU ELPA, disregarding the fact that Emacs already has a built-in
version of the same package.  Sort of a package-local version of
`package-install-upgrade-built-in'.

I am not familiar with the use-package code, but it seems like we could
implement this generally in package-install, by checking
`package-pinned-packages'.
