While I'm all for multicast support, I don't think this is it. TunSafe
only has that option to allow you to turn off an extra anti-multicast
filter that's on by default and drops anything incoming from ff00::/8
or 224.0.0./3, even if it's from a peer with those ranges in its
AllowedIPs. (Actually, 224.0.0.0/3 is technically the wrong range for
IPv4 multicast; that's 224.0.0.0/4. The upper half of that space,
240.0.0.0/4, has been "reserved for future addressing modes" since
1989.)
Yes, I also agree that all-or-nothing is not the right answer. I'm only
pointing out that multicast has been implemented in at least one client.
