There's actually still plenty of insane things about None in Python. https://peps.python.org/pep-0661/ is a great example of that.

> Sibling comments mentioned Option types, which are assumed the currently best approach

Option types are actually just the tip of the iceberg though. The real power is in languages that support algebraic data types. Option is just one common example, used to distinguish between just Some and None, but it's reasonable to have an enum with other states, each optionally with its own associated data.
