The usage has changed. The "of" is omitted that would have formerly been there.
That is a difference in grammar, not vocabulary.
Government[1] is a property of words often documented in dictionaries.
Are you arguing that grammar is not part of usage? I'm not sure I understand the point.

I've heard it used without the additional words, e.g. "They left... because." in which because is meant to mean "for reasons mysterious to me" or "for reasons that don't make sense but whatever."
> because : by reason of : because of — often used in a humorous way to convey vagueness about the exact reasons for something. This preposition use of because is versatile; it can be used, for example, to avoid delving into the overly technical (“the process works because science”) or to dismiss explanation altogether (“they left because reasons”).
The whole point of a phrase like "because reasons" isn't the use of "because", it's the overly succinct description that follows. "because"'s usage hasn't changed, just acceptable sentence structure.
