Murray, this is an absolutely basic bit of philosophy in protocol design.  It 
drives lots of decisions.

Unfortunately, historically, this is exactly the logic that adds useless bloat 
to protocols and causes interoperability problems.

When a feature is not currently used, it tends to be badly implemented, since 
it 
isn't exercised.  By adding it later, you are ensuring that there is a real 
need 
and, therefore, real end-to-end testing.
