Well, I believe that a warmup lap and the hot lap itself all make part of an strategy, and they do make part of the game.
While I agree that a warmup lap on AS GP with UF1 would be extremely boring, IRL we don't have perfectly pre-warmed tyres, nor start from where we want, and the way that you do a warmup lap have impact on setting up the car.
So, I still prefer the "the most realistic, the better" way that LFS started to be developed, rather than keep some "flaws" that can make the "game" more fun.
Once on a national championship I remember that on qualify I brought the car to the pits after my qualifying lap, parked the car inside the pits, and then I realized that I didn't need that. I was so focused on the racing atmosphere that I almost forgot that I was on a simulator. And honestly, it was fun.
