Yes.

One. And only one.

Why? 

Let’s suppose that we choose N (or fail to choose).  Different networks will make different choices. Then vendors will be forced to support all N of them. Chip manufacturers will have to support all N of them. Effectively forever. Sure, some may fail, but by that point it becomes impossible to remove the support without re-verifying the chip. So no one will.

Choosing more than one is hideously inefficient for the entire industry.  Our job, as an SDO, is to make a single standard.

The IETF is neither a coffee klatsch nor a publishing house.  Our duty is to make the tough decisions for the world.
