Workaround

We’d probably want to warn user that stable keg is linked and suggest user unlinking it. After the keg have been unlinked we should be able to install any version that is newer than the latest version installed in the Cellar e.g. HEAD or devel.

unlink + install -> succeed, and prior version is kept upgrade -> succeed, and prior version is kept uninstall + install -> succeed, but prior version is removed due to the uninstall

Makes sense to me 👍
