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.
