The tails people (iirc it is a tails project, who are hosted on boum.org infra) are generally okay with questions, I think you should ask about wether it's GPL2 or GPL2+. We could also ask them about the state of MAT, as once upon a time they used to include it in Tails.

I'm all for making it less hard for a package to get initially into Guix, but shouldn't at least hardcoded paths that make an often used function(?) be fixed first?
