That is one interpretation of his message. Another is that 
implementers are likely to do as little as possible and do things 
that we would agree are lazy. Mark's list of possible equivalents 
could just as easily show non-interop due to lazy application/IME 
implementers as it could to wild/crazy ones.

The IETF has a much richer history with lazy and/or rushed 
implementers. It would be good for us to keep them in our thoughts as 
we craft the documents.
