I would prefer that it gets spun off the test net, but it should stay on the test net for at least 1 more year, maybe 3 more years.
Really up the Hag/Dev. But yes I support the spun off ... eventually happening.
The other thought is going for big blocks so an asset layer could be built on top. But not so hot on that idea any longer given that there are lots of other new options out there to do something like that.
Right now I think it is best to view PRo as Uno#2, and that perhaps we can start launching a new chain each year in this vain of thought
Thus the propose of PRo is managing these launch projects.
