It was a non-blocking comment, and from the perspective of how the
document is written I guess it is not at all necessary to do any
changes. From my perspective it is a relevant observation that although
multipath is not a solution for the multihoming a network, multihoming
with provider addresses is a benefit to multihoming protocols. Which
indicates that if this should be added it is likely in the introduction
section or not at all. Your call.
