What is up with all these Demos??

Can't help to notice that since December 2022, the Playable compatibility has gotten nothing but Demos and Trials. 
I'm always hoping to see some new great games at playable state, but more and more demos appear.

Why is this?

Honestly, who cares about demos?

Demos are extremely useful to test the emulator with as you don't have to source the full game.
Either way, the emulator is made for every game/application that ran on PS3, not for full commercial games only, so we're interested in tracking everything.
