Hello Michael:

Could we leverage the use of RPL information draft to indicate that the RPL info can be safely removed on RPL packets outgoing the domain ? I think that would pass.

We can also indicate that insertion in allowed on incoming packets and see what pushback we get now.

This would avoid having too many flag days as the rules become more realistic. The times they are a-changing..,

You're saying that I can be exchanging data between motes in the mesh

headers en-route, i.e. without IPIP?

We did not say that in useofrplinfo!

Pascal is, I think, overstating the compromise/ambiguous text in RFC8200.
