Comment (by mindctrl):

 The attached PR is in good shape with great test coverage. There is a
 remaining question about back compat. I'd personally like to see this
 land. Given the function name is `add_post_type_support()`, I would not
 expect that someone adding an additional feature after I've added mine
 would result in mine being wiped out.
