With SO_REUSEPORT we should be able to run multiple listeners for incoming messages and handle those. This comes with a couple of ifs:

I don't yet know how to do this
Maybe Go's net.* is not fast enough - fix that?
There might still be lots of low hanging Go userspace code in CoreDNS and Go DNS, so that we don't need to go this route.

See some experimental stuff from @asergeyev https://github.com/asergeyev/go-toys/tree/master/reuse which looks very interesting.
