[CPN] proposal to eliminate apomorphy-based definitions

[Kevin Padian]

Dear Phil and Kevin,

I'm happy to support delaying the consideration of the apomorphy-based

it has been discussed before; the Paris meeting was some time ago and
perhaps there should be general weighing in from the community.  -- kp
