Yes, that is of course the point. There’s an infinite number of possible later versions to check for. The suggestion to poll for new versions using cURL was sarcastic. These “conventions” you speak of actually get handled by... package managers! If not everyone who hosts a package needs to “know” about magic files and make sure they make it following a spec that isn’t enforced by anyone and doesn’t break immediately but rather much later when someone tries to update. It’s like everyone managing their own database row with an informally agreed upon database schema.
