The discussion on the name change came from Łukasz https://github.com/python/cpython/pull/18239#discussion_r380996908 I suggested "GenericType" to be in line with other things in types.py. On Mon, Feb 24, 2020 at 8:39 PM Guido van Rossum <guido@python.org> wrote:
I can't find it right now, but IIRC somebody commented that "GenericAlias" is a somewhat odd name. I didn't spend much time thinking about the name, I just took it from `typing._GenericAlias` (which has a similar role).
