We (Cenk, Matthias, Thomas, and I) just got a short paper accepted at
ACM ICN 2020, that visits ICNLoWPAN in combination with
draft-ietf-6lo-fragment-recovery. Many of the findings there, are also
applicable for draft-ietf-6lo-minimal-fragment.

The paper will be publicly accessible soon, but to give a short preview:
The problem with fragment forwarding is that it effectively bypasses
en-route caching, as the fragmented data chunks are never presented to
the ICN layer. In our short paper we present a simple cross-layer
extension to 6LoWPAN Selective Fragment Recovery that allows to have
both fragment forwarding and en-route caching.
