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.
