I'm not sure I agree.  I can see legitimacy in the idea of an expert 
mode which, if selected, does reveal the raw data.

I guess we're running into a blurring between "sender" and "signer".  Is 
this a major point of concern?  Or is it sufficient simply to define my 
use of "sender" to include the "signer" case, perhaps citing DKIM as an 
example?

But as you stated, 2822 does say that the order should be preserved.  
It's fairly unambiguous about that.

Are they not?  Your changes alter the IP addresses, but RFC2606 doesn't 
say anything about IP addresses.  However, I've changed example-isp.com 
to example.net as you suggested.
