Yeah, I do indeed have nothing useful to say about Once, basically, because it doesn't seem very useful except as a raw implementation primitive of OnceLock. I suppose we could add a comment that soft-discourages it?

@workingjubilee thatnks for the PR!
The question of Once vs OnceLock seems to remain unresolved though. If Once is to OnceLock what Mutex<()> is to Mutex, then it should probably be considered extremely niche as one can't even safely protect any data that way?
