Anyways, if you can't tell, my philosophy is simple.
Let a hundred protocols blossom.
Don't discourage people from doing interesting projects with protocols, even if they aren't what you would do. Encourage experimentation and encourage play.
Going back to something I've talked about in union organizing: if someone is willing to _do work_ the goal is almost always to encourage that work and find ways to help make it productive, not shut it down before it has had a chance to breathe.
There's plenty of time for criticism and for deciding how things will work, but it is incredibly hard to know what will work ahead of time.
Even if a protocol is 95% bad ideas, in the 5% of cases at the edge there might be something _truly_ worthwhile that you can use in another effort.
Or maybe what you'll find is that what they are doing is solving a problem that another protocol _can't_ solve, or at least not solve cleanly. Different designs serving different purposes.
