Yes, but I have not idea how it could be implemented. Debian ELPA packages share similarities with built-in packages, leading users to potentially overlook automatic upgrades. If a user chooses to manually upgrade these packages, the 'describe-packages' cmmand should perhaps indicate that they are "shadowing an external package", similar to the behavior displayed for upgraded built-in packages. The function '(package--user-installed-p 'debian-el)' returns nil, indicating that, according to Emacs' perspective, Debian ELPA packages are not considered user-installed packages, and I don't think they should be upgraded without not respecting 'package-archive-priorities'.
