Adding to what Simon said, dependencies in Python are an absolute mess, with no truly reliable mechanism other than saying "here's a list of what you'll need, go install it all manually". So every additional dependency is a major burden in terms of packaging, documentation, learning curve for newbies, etc. and we try to avoid inflicting that unless it's absolutely necessary. (though personally I think I'd prefer to outsource crypto to, you know, people who actually know how to do it)
