Mostly out of curiosity, does anyone know if CC runs are accepted? I would assume not due to the many options with reducing slow down, rewind feature, etc. requiring more categories than anyone would choose to deal with. Frame rate specs are something I struggle to understand but figured they apply.

They are allowed. All of the stuff like reducing lag and rewind isn't allowed, and neither is save state loading. If enough interest was shown a category option could be made available for allowing slow down removal but so far nobody has shown any.
