You tell me.  

1) how can a node that another node is a neighbour?   don't forget mobility,
   and don't forget about wormhole and sinkhole attacks.

2) given an industrial situation, with a series of installers who come and
   go, and who may not all be fully trusted by the plant operator,
   (I'm not making this up; see section 2 of rpl-industrial-applicability-02)
   is there some advantage to being able to program neighbour cells?

   Consider an installer that wants to skimp on those expensive high-gain
   antenna, powered relay/router nodes (the ones that require that they spend
   3 days pulling electrical power through the plant), could they achieve the
   specified deterministic performance by taking many more slots than they
   ought to have?

I'm just leaving your credentials here, because I think you have more
connection to the people in the field than I do.   

Do you really trust EVERY SINGLE NODE in that link?
On the subnet?  
At the site?
