Yeah! You got it in one! That is where we are now, and it will steeadily
evolve into what we want it to be.

No. It is trivial. You add nothing.

So? There will not be many such sites until the newer software is widely
deployed. In fact, I don't see why there should ever be such sites since,
when the software IS widely deployed, there will be very few such cancels.
A seamless transition from the old to the new, in fact.

Yes, but only if a world-widely-recognised system for granting such
