Considering these stuff was hold back from GT Sport, there's a good chance we will see them in GT7 considering it's a full gran turismo game with also single player mode and simulation mode, so online they can put the options and enable it if players want to use it in lobby, while in simulation mode give that options so the game become more realistic and better. It's not something that makes the game too complicated, the game it's still simcade but with temperature and stuff it gives more immersion and depth which I whink is needed, because only tyres, suspension damage and fuel are a bit poor as variables in a race, especially endurance and 24h races. We had these options in gt sport beta, there's good chance they will implement it in gt7 or if not at launch when updating the game at some point
