I think I have no problem with the above (I mean I will not argue in
favour of changing this).

Correct. However I originally noticed that this "feature" also works by
adding a Reply-to: in the header...
My point at the RIPE meeting was that when sending an update with a Reply-to,
the mnt-nfy DOES get a "warning" message, that somebody made SOME updates,
(since the "Congratulations" are sent to her), but has no clue wrt. WHAT
exactly has been modified (usually the Subject: line does not provide accurate
information - if at all)...
(Of course, the situation can be even worse if the From: line is forged...)
If I remember correctly, at the DB-WG session the absence of the notification
(in the Reply-to case at least) was considered a *bug*.
I still incline to consider the "Reply-to case" a bug (or *unwanted* feature).
Forging the mail header is usually less trivial than adding a Reply-to.
The latter can even occur inadvertently (this is how I discovered all the above).

PS. I suppose (and strongly hope :)) the authentication is based on the From:
and not the Reply-to:.
