The AirPlay version switch feature proved to be too unreliable, especially going back to 2 from 1 so it was scrapped.
Here's a thread that discusses that.

Thats not to say a dev couldn't create a new, more reliable way to do it but there hasn't been any interest so far and my plate is already overflowing with TODO items :-0
As far as AirPlay itself goes it looks like version 2 provides benefits to Apple's IOS users by (1) greatly reducing audio glitches by using AAC compression and a more efficient non-realtime packet delivery scheme, and (2) delivering multiroom sync audio capability right from the phone. Their users prolly really like this assuming the app they are using is sending AirPlay 2 format.
In doing this Apple made it almost impossible to know whats going on with the format of the audio stream, and users that want to know are forced to refer to some spreadsheet of apps, os's and protocols to figure it all out assuming the information is even correct.
For example I've read that Apple Music on a Mac using the OS level AirPlay still sends the AAC (lossy/buffered) stream to an Airplay 2 endpoint. Thats not true at least for shairport-sync. I can see in the shairport-sync log that the stream being received is "AP2 Realtime Audio Stream" which is the lossless ALAC format.
Another aspect of the AirPlay 2 system is the rehashing of the old "lossy vs lossless, can you actually hear the difference" arguments on audio forums...
