I could ask why normal merge produces notification, after all the user
has to check status and diff to ensure that the merge got applied
correctly.  Does that mean the normal merge notification is of no use?

The obvious case where record-only notifications help is when the
merge doesn't change anything, because I got the wrong source URL or
revision.  If I'm expecting to see a change and I get no notification
then I know I made a mistake.

I was thinking just the U line.
