The main problem for developers isn’t that it’s hard to implement. It’s the fact that EAC runs in userspace on Linux and is pretty trivial to bypass.
With that said, I want Linux to be THE gaming platform. Problem is that server side anti-cheat is not as widespread in gaming as it should be.

My suspicion says that Valve use AI in VAC these days. I have no proof of anything but in my opinion it would be the smart thing to do. And something major happened in TF2 a few months ago where they finally managed to ban the rampant bot cheaters. Could be AI or it could just be Valve finally taking the problem seriously.
