I'm not sure what your point is. We don't exactly know what will be kept the same and what Larian will change in the future. Personally I don't like cheese because I like to be immersed in the game and cheese is usually something silly / goofy that makes it hard for me to take the game seriously.
One example of a cheese is that you can kill anything with barrels, there is a solution to this - make enemies notice barrels, move away from them, throw them away or warn the player to get those barrels out of their face or they will attack. This is feedback. Is it a given that Larian will change / add such a mechanic? No, actually most likely nothing will change in this regard and you will be able to beat any encounter with barrels. Same for hidding cheese, it can be solved by making enemies properly scout the sorrounding area looking for the player. Once again, it is not a given that Larian will add such a mechanic.
Given the level of modification Larian has put into moving their interpretation of 5th edition towards "cheese" tactics, and including DOS surface/barrelmancy, etc, I wouldn't expect any significant changes to what they've made the core tenants of the combat which are the use of height for advantage, and the environment.
It's about as far from what DnD combat actually is, but it's what Larian seems to have settled on as their vision for BG3.
