  Maybe a more formal way to express my concern: it should be easy to
come up with (of course ugly or expensive to verify) rule modifications
that would still allow >99.9% or more pro games to be valid, but
invalidate games proving these results in just a few moves.  Can we
reach some results (re longest games, number of games, etc.) that
don't have this property?
