They must be scrambling for ways of applying their tech now that their main cash cow has been subsumed by Catalina. But I don't think this is it ...
I recently found another use case for my Luna display by the way, when I wanted to play some real-money online poker in the garden (shelter in place makes you want to do things like that ;-). Apple does not allow gambling applications on iOS, and screen sharing Pokerstars on my Mac Mini using VNC was a really shitty experience. So what I do now is start the Luna app on the Mac Mini, connect the iPad to it, then take it out into the garden (which has its own wifi AP) and put it on full screen. Responsiveness and touch control are excellent that way.

In this case, SideCar is enabled on newer Macs (Catalina) and iOS 13, requiring people with unsupported Macs or iPads to upgrade their hardware to these requirements [0] which is unnecessary for this feature when AstroPad supports older Macs, Apple Pencil and iPads on the minimum requirements. [1]
So, yes. Hardly sherlocked, unlike several software only companies who get completely sherlocked in all areas every WWDC.

Since Air Display was not part of macOS and was not created by Apple, we could probably say that Air Display (like Duet and Astropad) was Sherlocked by Apple/Sidecar.
That being said, it's a pretty obvious feature that I've wanted since the first iPad. I started using Air Display when it first came out, but it always felt clunky and I wanted a simple wired solution that was included in the box and "just worked."
I'm still waiting to see how ipadOS evolves, but I'd would consider using using such a setup with a mac and a surface go.
RIP Target Display Mode. ;-(
What do you mean by this statement?
Personally I'm extremely happy with Sidecar and being able to use an iPad/pencil as a smaller Cintiq.
(That’s ignoring the new weekly crashes that the virus/firewall scanner now causes... which is another story).
Your use case seems to be different.
I've been trying the built-in screen sharing VNC, and that too is very laggy.
The Mac mini has tested fast (iperf3.. latency and bandwidth are good) over WiFi, so I think an app has the potential to be fast.
