I think that there are three points of view:

1) ANIMA won't run on class 2 devices anyway, and bigger devices can just do
   HTTPS/EST.  Why complicate my life?

2) The CoAP mechanism is not well enough defined as yet, so we don't know
   what it even means.
        Options are:  CoAP/DTLS, CoAP/OSCOAP, CoAP/OSCOMP/CoMI (device is passive)
        IPIP proxy mechanism not well enough defined, so what does that even mean.
   Best to stick with things we know.

3) MyCompany wants to do mechanism X rather than CoAP, so if we can't have X,
   then let's specify a method too big for small devices, and in market
   confusion for small devices, MyCompany will dominate.
   (where X is various mixes of 1x, EAP, PANA, Thread, ZigbeeIP, etc.)
