This is true for existing users of those operators.  New names are
much easier to get by the new users.  We are using them on all other
datatypes.  Datatypes like JSON is more popular than inet.  Many
people already know what <@ and @> mean.

I think we will immediately get benefit from the new operators because
of other reasons.  Repurposing them in far future was a minor point.
I though having a long term plan on this minor point is better than
having no plan.

It is a fair position.  Anybody care to vote?
