I don't think the conclusion of this thread is necessarily "don't".
The right form of config option, especially if there's consensus on
what it should look like, is a very viable path, and the IP_PKTINFO
thing you found makes the implementation a lot simpler.

Having input from experts on the mDNS side would be most welcome and
sounds like a good next step to figuring out if this makes sense.
