Ansible modules are a bit.. special.

They're executed directly via the python interpreter after having some
glue code from Ansible itself copied in. So they're really just CLI

That said, you still have to tell the users to use Ansible and the tool,
so that would effectively inhibit the way the project may be distributed.

Agree this is probably more for the legal list. :)
