Good point. I think there will always be concerns about how mobsters are portrayed, because there needs to be a degree of honesty about why they get drawn to crime in the first place. Goodfellas for instance does a very interesting balancing act between showing why Henry Hill is attracted to that world, whilst also showing the appalling cost of his actions.

As for The Godfather, I do think there is a case (though far from a watertight case) to be made about the first film potentially glamourising the mob, at least in certain segments, not the film as a whole. But even if you do believe that argument - and I don't think it was Coppola's intent for one second - that argument definitely doesn't apply to the second film.
