This was considered as part of SERVER-76042. It would simplify most of the call sites who just 'uassertStatusOK()' anyway, and will also simplify some of the implementation. It also allows the linked follow-up ticket.

Warning: I attempted this and the patch got quite large. It is conceptually simple though and there wasn't anything that came up that seemed super risky. There were a couple try/catches to preserve behavior in an "if not OK" branch, but I recall it was exclusively error message context, and perhaps breaking a retry cycle in one place.
