te 4.7.0 breaks Mypy daemon on Python 3.7 (`TypeError: metaclass conflict`) about typing_extensions

[JelleZijlstra]

This was fixed in mypy recently (python/mypy#15543) but not released. Given that 3.7 has reached its end of life, we're not planning to fix this in typing-extensions.

[JelleZijlstra]

typing-extensions 4.7 generally works fine with Python 3.7. It's broken only when using dmypy (not mypy itself, which apparently doesn't use any TypedDict), or potentially with other mypyc-compiled applications that use TypedDict. A relatively obscure case in a single third-party tool on a version that has reached end of life isn't enough to justify yanking the release.

Thanks for the fast response.

Could you tell me why typing-extension 4.7.0 is stilled tagged with requires-python = ">=3.7" then? Would it make sense to yank 4.7.0 and 4.7.1 and update that to >=3.8?
