Right. It'd be nice if you fixed the typo as well if you for some
reason re-spin this.

Fair enough. The "errors" or "notifications" indeed don't tell if this
specific function has failed.
So, if you feel the @rid is not documented well enough, maybe add a note in the
respective parameter documentation instead of leaving it alone at the
bottom of the doc?

Well, I don't have a strong opinion on this so you can keep the RB tag
also with the blank line.
