=> Yes, but my point is, this will happen independently
of deprecating a bitstring. The /16 itself is meaningless;
what we're arguing about is the use. So removing a /16
will not change anyone's mindset, it will just make 
things more unpredictable.

=> Exactly, there is clearly no concensus on that.

=> So let's have a shot at a BCP. It seems like 
a more productive step than the infinite loop that
we're in right now.
