No, because the MUA will in fact trust the header (when it carries the
right "authserv-id". Otherwise it is completely useless to the MUA.

Sorry but I think that asserting a truth like that and that simply is entirely 
unfounded.  Since there is no MUA precedence for this header and since I don't 
even know what it means to say "the MUA will... trust the header", I think that 
statements about the details in handling the information need to be moderate 

I do not wish to be a troll, so unless my point is not clear, I don't
want to repeat myself. Having made the point about as well as I can,
if it is broadly believed to be out of scope, so be it.

I think your concern has served to prompt more clarifying language.  Given the 
nature of this mechanism, more clarifying language is almost certainly a Good 

IMHO, this issue deserves specific discussion in the Security
Considerations, because, while it is not deep, it is not entirely obvious.

I agree.
