I agree with this. I have no problems with changing the draft 
(which as Leandro already noted is "work-in-progress") to specify that 
both HBO and NBO are permitted over the wire, and that it is the
topology server's task to keep track of which one is used.

Remember, permitting both is a superset of the current one (NBO only)
so it is fully backwards compatible. We break absolutly nothing by 
permitting this.
