I know that CoG has contracted sensitivity readers on occasion; when being edited as a CoG author, I’ve had suggestions about phrasing changes.
There is some info here about the CoG house style and how it relates to inclusion which may be of interest. There is also some requirements in the house style about not using lazy/offensive stereotypes. While Choice of Games projects require the ability to play as varied genders, Heart’s Choice and Hosted Games don’t. Choice of Games and Heart’s Choice have editorial oversight whereas Hosted Games does not in the same way.
