Who is the tool: the programmer or the program?

I'm using typeshed_client to get the typeshed ast stub file, then I'm doing ast things to the file, and I am writing extra code to accommodate these three things

typeshed/stdlib/ast.pyi

Lines 1495 to 1498 in ecd5141

	# Without the alias, Pyright complains variables named pattern are recursively defined
	_Pattern: typing_extensions.TypeAlias = pattern

typeshed/stdlib/ast.pyi

Lines 1196 to 1199 in ecd5141

	_Slice: typing_extensions.TypeAlias = expr
	_SliceAttributes: typing_extensions.TypeAlias = _Attributes

which made me wonder: ought we disfigure a universal tool (Python's official stub file) because of a third-party validator's error?

Does the code validator serve the code writer, or do we write code to appease the code validator?

I believe a uniform, predictable stub file is better than coding around a false diagnostic report. I propose removing the three TypeAlias.
