At the moment we do not use 802.15.4 primitives in our sensor network
deployments because we mainly have star networks of a few nodes with known
addresses and no need for scanning/association/network formation.... We are
going for larger-scale networks.
I wouldn't mind utilize 802.15.4 primitives for 6lowpan commissioning /
bootstrapping because 6lowpan is based on 802.15.4 and the present
primitives can do a lot, the processes are already defined and very often
already implemented in the nodes.

Because, in practice, many vendors use the 15.4 frame format and
mechanisms as a link layer, but do not use its MAC layer. So assuming
the MAC tie us closer to the link layer than may be necessary or
advisable, and preclude adoption by a broad range of users.
