MyPy does not support subclassing function a argument member with type type though pyright does (e.g. pyright 1.1.414) #22337

Hello MyPy team. Thanks for the great tool.
Sharing the following behavior which appears inconsistent with handling of arguments of type type (normally can be subclassed) and which is inconsistent with the other popular typechecker Pyright (e.g. commandline pyright 1.1.414 ; or latest on pyright-play.net )

Bug Report

MyPy does not support subclassing function a argument member with type type though pyright does.

Consider the following example in the Pyright playground (typechecks there):
Code sample in pyright playground

class Person():
    def __init__(self, name: str, age: int, characteristics: type):
      self.name = name
      self.age = age
      self.characteristics = characteristics

def foo(person: Person) -> None:
    reveal_type(person.characteristics)
    class Sub(person.characteristics): pass

If one attempts the same in MyPy 2.4.1
MyPy produces an error attempting to subclass person.characteristics though MyPy recognizes the type as builtins.type:
https://mypy-play.net/?mypy=2.4.1&python=3.12&gist=0ecda4fd36c9338c128ae16e69750463

class Person():
    def __init__(self, name: str, age: int, characteristics: type):
      self.name = name
      self.age = age
      self.characteristics = characteristics

def foo(person: Person) -> None:
    reveal_type(person.characteristics) # N: Revealed type is "builtins.type"
    class Sub(person.characteristics): pass

output:

main.py:8: note: Revealed type is "type"
main.py:9: error: Name "person.characteristics" is not defined  [name-defined]

(MyPy reveals the type of person.characteristics successfully but says the name is undefined when attempting to subclass)

(And the same on the latest master

This is despite subclassing arguments of type type being generally supported, e.g.
https://mypy-play.net/?mypy=latest&python=3.12&gist=40c549b7acb527d213518171db016ca7

def foo(a_type: type) -> None:
    reveal_type(a_type) # N: Revealed type is "builtins.type"
    class Sub(a_type): pass

is fine in MyPy 2.4.1 .

Thanks!
