I was going to quibble about using 'SHOULD' because it is so forceful, and
that a 'MAY' would suffice, but you are raising the larger question of whether
it is appropriate to have normative text at all.

I think that the real-world need is satisfied adequately while avoiding the
pitfalls of being normative, in this case:  Add advisory text that notes the
issue and describes how to resolve it.  But make a point of using no normative

gatewaying between Internet mail and Netnews.  A thoroughly laudable goal, but
not one for RFC2822bis...
