> However, for link local addresses, especially in a route-over mesh where a link-local IP packet travels strictly one node hop, it does not seem as critical. As mentioned below, in many cases 6LoWPAN compression relies on a one-to-one correspondence between a link local and IPv6 address to provide effective compression.

Indeed, and a more complete approach to fix the privacy leaks for the link-local cases will involve privacy enhancements to the layers below (as discussed by Piers O'Hanlon at IETF 89 and see also https://www.w3.org/2014/strint/papers/35.pdf).
