Indeed.  Hence "in normal use", to reflect the guidance of RFC1123 -- maybe
I should have said "in recommended use".  And my use (below) of "impose
[...] restriction" was ill-chosen.

Again, agreed.  But in the same way that it's useful for RFC1123 to provide
guidance, would the fact that the relationship here (between relay and
next-hop) is different to common SMTP not suggest some alternate guidance
is appropriate?

I am not trying to argue the technical content, just to clarify it.
