> There isn't any difference between shallow-cloning a tag vs. downloading it in a tarball.

Yes there is, we have checksums for the tarball.

Package policy is documented in the Manual; many other packages use submodules by downloading each tarball and moving to the specific place.

> And AFAIK GitHub doesn't allow you to download a tarball for an arbitrary commit, only for a tag.

Did you try? We use this functionality in multiple places.

Anyhow, the issue with being "packageable" is that if writing a reasonable template is too much trouble, then it isn't packageable. It isn't that it has submodules or anything else.
