This is setting a, in my opinion, rather bad precedent.  Next we'll
be adding various modules here due to various reasons.

I think this case should be pure political now, not technical.  Ie,
if some project declares itself as GPL, it is not kernel task to
verify that the sources are available or to enforce that.
