Another reason to create a separare python3-blends package... that
script should be convertible to use it.

That is the main idea of the rewrite.

Check out https://ole.ath.cx/blends/ which is generated from the
blends-gen-dev source. Does it fit your needs in terms of functionality
and documentation?

We already have git, so creating a function that returns a
`blends.Blend` object based on some git tag (rep. Debian version) is
straightforward with `git worktree` and also (since the blends source
packages are rather small) quick. And has the advantage that you don't
need to maintain an additional json file. You can just generate it on
the fly ;-)
