Hm, I thought I responded but apparently not...

This change to scope 0x03 is not just for MPL, so we don't know how else it might be used in the future.

Specific examples:

1) two adjacent RPL domains, which do not share a prefix but are to be considered as one realm for mDNS
2) one RPL domain and one other non-RPL subnet that are to be considered as one realm for mDNS
