James - Thank you for finding that. I was trying to hunt down info on it since the mdnEXT draft appeared to have expired in January 2014- https://tools.ietf.org/html/draft-cheshire-mdnsext-hybrid-02 - so thought it turned into a case of Apple publicly saying "sure, we'll work on something. Did so for a little bit, and then just let it not go anywhere - dry up quietly - and leaving the Apple discovery issue back to the Wireless Educause Admins - or pushing that folks should be using the "BLE" methods or a "sonic detection" like the ChromeCast PIN or Zoom Room - in room sharing. But to see that there's still work/activity/development into it is a bit nice - and as you described - a slow process.
Ricardo - We actually do make use of Aruba AirGroup - and agree with what you described about devices having to be registered, limitations of wired vs wireless, and ways of making it work. The method you mentioned about both screens is the workaround some of the Techs have been using and seems the way to go. Thank you for your input and have a good weekend!

The Extensible Scalable DNS Service Discovery working group was formed at the IETF and eventually various RFCs have been published https://datatracker.ietf.org/wg/dnssd/documents/ but I don't know of any actual implementations. OK I read RFC 8766 (Discovery proxy for mDNS DNS-Based Service Discovery) and it says DNS Push Notifications (RFC 8675) is implemented in iOS 13 and macOS 10.15, and there's several test implementations of RFC 8766 but nothing I'd call production ready. So that's what you get after 8 years of the standards process, which is about how much progress I was expecting when this all kicked off.
