It seemed to me that the key point of Johnny's original note was that
gee, there exist these checksums with different error detection properties
that *might* be interesting for certain applications using TCP.  Could
there be a way to use a different checksum?

It seems to me that's a perfectly fair question to ask -- and the answer
appears to be yes, there's a straightforward way to negotiate a new checksum.

Whether that's a good thing or not, is entirely separate.  As some folks
have pointed out, there's always this problem with new features -- some
idiot decides the way out of a problem (e.g. broken hardware) is to use
the new feature instead of fixing the proper problem.
