IMHO: 4) Use mild filters (e.g. allow a /32 to be disaggregated to /36's) and send a polite email to the POC to the effect of, "Please beware that because you have not offered a covering route matching your allocation, your IPv6 network is not reachable from ours. IPv6 is not IPv4: end users requiring /48s for multihoming should get them directly from the RIR. For complete Internet connectivity, we strongly encourage you to offer a covering route."
