Yeah. A while back I was poking through some unfamiliar code and noticed that my editor was rendering a use of `datetime.utcnow()` as struck through. When I hovered it with my mouse, I got a message that that function had been deprecated.

Turns out my editor (vscode) and typechecker (pyright) saw that `datetime.utcnow()` was marked as deprecated (I know one can use the `@deprecated` decorator from Python 3.13 or `__future__` to do this; I think it was done another way in this particular case) and therefore rendered it as struck through.

And it taught me A) that `utcnow()` is deprecated and B) how to mark bits of our internal codebase as deprecated and nudge our developers to use the new, better versions if possible.

Can you do it for functions defined by other people, or only for functions that you defined?

I'm thinking in the general case, but motivated by this example of a 3rd party function that accepts a SQL query as a string, and we'd like everywhere in our codebase to stop using that and instead use the 3rd party function that accepts the query as a t-string
