Well, my point is that you currently don't have to inherit from int (or IntEnum) to get an int method on your Enum, which is what I find questionable. IMO conversion to integers should only be defined for IntEnums. (But I haven't followed all of the discussion and this may already have been decided.)

Good point. I think this may be just an artifact of the implementation - PEP 435 prohibits implicit conversion to integers for non-IntEnum enums. Since IntEnum came into existence, there's no real need for int-opearbility of other enums, and their values can be arbitrary anyway.

OK, I'm stupid -- I was thinking about moving the int method to IntEnum (that's why I brought it up in this part of the thread), but as a subclass of int itself that obviously isn't needed :)
