Slightly off-topic, sorry
A friend of mine emailed me today to say that he'd seen a tweet suggesting that Unity was making a comeback:
Ubuntu Unity Remix
"Good news for all Ubuntu Unity lovers! We're an Ubuntu daily flavor now and our ISOs will now be built daily with all other flavors and uploaded to http://cdimage.ubuntu.com. Ubuntu Unity 22.10 Beta will be our first release as an official recognized flavor (Sep 29). YAY!"
I don't know how much truth there is to it.
And I presume they're talking about Unity7 rather than Unity8, though some dev love for Unity8/Lomiri would be much appreciated.
