IMAP doesn't report transient errors (which is perhaps wrong, but that's 
how it is). The server has no way to report transient errors for the other 
dozen or more FETCH items. Why makes this one different?

IMO, the document shouldn't mention transient errors at all, since they're 
alien to IMAP and orthogonal to this extension.
