[int_19h]

What would be the point of dual licensing GPL3 and MIT? So far as I can tell, MIT is a strict subset of GPL3, and any GPL3 project can use it anyway.

Releasing it under MIT too would allow it to be used in closed source software projects. GPL does not allow that use case.

I think the point int_19h meant is that you don't need to additionally license software under GPL when you already license it under MIT
