Pascal, thanks for starting this process!
I'm going to wait for Huimin to add his name to the author list, and
then I'll push an update document.

Your text puts both values into a single Metric.
I was thinking it would be two metrics, but upon reflection, it probably does
belong in a single metric object.

What would an appropriate default be if the metric is introduced in the
middle of the DODAG?
   https://datatracker.ietf.org/doc/html/draft-ietf-roll-enrollment-priority-03#section-2.1



doc> The size of the DODAG is measured by the Root based one the DAO

doc> can only be used to infer a load in an homogeneous network where each
doc> node advertises the same number of addresses and generates roughly the
doc> same amount of traffic

I really that we would measure in terms of number of routes.

I concur that we will get comments, and yet, I think that we really do want
to allow for "future work".
