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

https://github.com/python/typeshed/blob/ecd5141cc036366cc9e3ca371096d6a14b0ccd13/stdlib/ast.pyi#L1495-L1498

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.
