"I would be quite happy to port stuff, but why the hell should I bother if the minute I release it I get emails telling me that I didn't include the source / GPL notice / that it's GPL and to expect a court summons?"
Just include the source and the license in your archive, and you won't get emails. Simple, really.
I suspect the main reason people don't include the source is that they are afraid their code isn't professional enough to be looked at.
