The circumstances are well described and the solution specified is sound from a transport point of view, and also it has a track record. The draft directs hosts to use the retransmission algorithm from RFC 3315, the DHCPv6 specification, which includes backoffs and a randomization factor. The draft specifies using this algorithm with no maximum retransmission count (MRC) or maximum retransmission duration (MRD) and shows that if there is an extended cause for a router to not reply, there will be roughly one RS per hour from each host.

The rationale is cited normatively from an individual internet-draft from 2012 but the correct reference (and the one that may be cited normatively) is RFC 7083. I find that the datatracker is missing a replaced-by that would have led from the 2012 individual i-d through the WG i-d to the RFC.
