We could also explicitly specify that this raises a TypeError, but I feel like this is generally known that invalid arguments raise TypeErrors?

Usually:
- Invalid signature/usage/object types -> TypeError
- Valid type but invalid data -> ValueError
The only exception I'm aware of is ipaddress which raises TypeErrors a bit everywhere...

Hum then not documenting ValueError would maybe make sense? I had the correct assumption for TypeError, and wasn't sure for value errors but indeed it makes sense and once you know about this you can just write your try..except blocks from muscle memory

I am actually fine with documenting this. Sometimes we do document this, sometimes not.

This is a trivial improvement that I think doesn't require an issue.
