package-vc can check out the latest revision that bumped the version tag
(which is what {Non,}GNU ELPA uses to create new versions of a package),
you just need to call `package-vc-install' with `:last-release' as REV.
So the technical means are there.

But if this is done, the question what advantage this has over just
installing a tarball this has?  You would almost always get the same
code.

Just to clarify, I am not vetoing anything here.  If the functionality
is added to use-package (which is up to the use-package maintainers to
decide), then I don't think users need to be infantilized with these
kinds of little ceremonies.  All I want to understand is the motivation
behind this feature in the first place.
