LGTM

> There is also TokenKind: this one does not currently inherit from BaseEnumeration and is defined somewhat differently, having all its variants and their IDs as a dictionary in enumerations.py. This seems quite arbitrary to me, is there any reason it is done this way? Otherwise I would also move this to cindex.py as another subclass of BaseEnumeration

I agree that this seems arbitrary. You think you can proceed with refactoring `TokenKind`.
