I think you're right.

If MUA's:

(a) merely check for the existance of AR (and ignore the hostname) then 
all AR headers MUST be stripped from incoming messages (I guess unless 
the MUA is programmed only to look at the top-most and that one is added 
by the local MTA)

(b) search for an AR that matches a known hostname then nothing needs to 
be stripped except AR's with that hostname on incoming mail

These are the two options that I can see.
