But looks like I hadn't checked what the MTAs actually write to the header when I added this feature to LMTP, and nobody had mentioned this before either. I wonder if anybody's system breaks if I just change it now..

If you do this Timo, would you please also consider going ahead and 
adding the 20 or so lines of code you said it would take to also add 
support for the x-original-to header (this specific was in a private 
email to me while our support contract was active), as we discussed on 
this list - and you then discussed with Wietse, back in April or so of 2012:
