You won’t see those releases and the ones that are are highly edited to remove perceived racist scenes and “violence”. Just watch the reruns on Nickolodian station to see what they’ve done to them.
These discs do start playing with a “some of the content is racist or otherwise objectionable; editing this out would be worse than showing what was historically acceptable at the time” warning ... though yes I have noticed a couple abrupt edits where I’m sure there was some really objectionable content. Of course, Nick would be obligated to edit more heavily for public broadcast than edits for a complete historical collection.
