@bluejekyll commented on GitHub (Sep 13, 2017):

Ok, I've decide the path forward is to split the NameServerPool into two, one for Datagram and one for Stream oriented connections. We'll query the datagram pool first, if there are no available Nameservers, then we'll query the Stream oriented pool. It will also give us the ability to easily specify that we want to promote a query to TCP in the event of truncation. I'll look at patching this in the next few days.
