We're in violent agreement.  When the data in an SF is changed, the
intent is that the resulting data is to be used to make a new
TCP connection.  If the data is corrupt/incorrect, things will go
wrong on that connection; preventing this is desirable and the
TCP checksum is deemed to be a sufficient preventative measure.
