Thus, I would think that desires of the authors of the RFC should have a heavier influence than the rest of us, although our input might be important inputs to them (and maybe to the Designated Expert). Maybe we should put the issue aside until we hear from them, which could be after the holiday.

We would recommend keeping the same numbers (19, 20, 21) since it 
appears that all existing implementations have made the correction.  
Also, we would prefer to keep RFC4753 and RFC5114 distinct since we'd 
like to keep a separate document as a Suite B reference.  If the 
inclusion of the three ECP groups in two different standards is causing 
confusion, it might be worth thinking about removing them from the 
upcoming RFC5114 update.
