I have read it. It seems like it is way overdue to have this work.

} The difficulty lies in the method of partitioning the traffic to 
multiple parents.

But, what about the cost of the downward traffic?  We have to attach to 
one parent or the other to get traffic routed right.  Maybe in 
non-storing we can do something smarter with projected-DAO?

It's good that [I-D.ietf-6tisch-enrollment-enhanced-beacon] is 
referenced.  But maybe 
https://datatracker.ietf.org/doc/draft-richardson-6tisch-roll-enrollment-priority/ 
also needs to be updated to
take into account the remaining throughput priority.

I think that the document would benefit from distinguishing between the 
cases where a node has already enrolled from the situation where the 
node needs to enroll.  The set of information is not the same.
