It depends on what is the offending part, but in general, no!
I already can't stand that some older animation from the likes of a Tex Avery for instance have been cut down to cut out things that are considered racist these days. Magical Maestro, Uncle Tom's Cabana... They are considered art. It's as if somebody would come with a tee to cover up the Venus from Milo, or paint a black bar over Adams crotch in the Sistine Chapel.
Warner Bros handles this quite classy.
