Just to add. I think same methods would be useful to have for strings as well.

Yes, 1. adding keyword argument for `pop` 2. implementing `get` method as it doesn’t exist at all * This wouldn’t break anything for sure. Well… theoretically could, but I find it hard to imagine anyone has written such code.
I like PEP 463. Looks simple and intuitive.

So following Chris’ logic... If there are 10,000,000 python users on Stack… And we assume, that every user encounters such need at least 2 times a year (being very speculative here, would say conservative?).
That was me being VERY generous to the other proposal :) At very best, what you're seeing is an *upper bound* on the number of people referenced, but I wasn't actually arguing numbers there so much as disputing the incredulity given.
HOWEVER: Your proposal is much easier to make backward compatible. Adding a keyword-only parameter to a method that currently doesn't accept keyword arguments is (a) not going to conflict with current code, and (b) will instantly error out if someone attempts to use this feature on a Python that doesn't support it, so it's not going to cause subtle errors.
Though, notably, this would count as another use-case for PEP 463, if anyone felt like reviving that.
