Ah, I think I get it now:

If I for example created a tag for the version of my package and creation of the
tag caused the VCS host to create a tarball as release, I could go the url-fetch
way and then I would use `guix hash` on the tarball, which is the release
tarball, but if there is no release tarball addressable using a URL, I would use
the git-fetch way, which means GNU Guix would have to verify the downloaded
repository, so I calculate the hash using the other way.

So it all depends on what I specify in my package description, about how GNU
Guix is to retrieve my package.
