I'm not sure as `SourcePackageType` exists and the types are `dpkg`, `rpm`, `ebuild` and `ci_build`. We can also reuse that enum but I don't know if that makes sense since it is used for the publishing history and releases and we don't want those things to support `snaps`, `charms`, etc. right?

Now it is more readable and efficient!
