And the more you hold on to that attitude that this doesn't "feel" like 5e the more you are doing exactly what i said by taking a "hard stance you are going to do nothing but bitch and complain about how the game isn't X." Or doesn't feel like X, it is the same thing.
Stop trying to get the game "feel" the way you want. That is a nebulas concept that means F'all because it doesn't have the same meaning for every person. Accept that there WILL be environmental damage that is part of D&D now, it has been expanded GET USE to it. It is not going to change. If you want Larian to remove environmental damage you are pissing into the wind and all that is going to happen is you are going to get angry and wet. This current version of environmental damage is extremely tame compared to DOS 2. You are not going to get it removed. That is the heart and soul of how Larian approaches combat.
I find the BG purist and the 5e purist to be a bunch of rigid uncompromising fans that simply feel they are right period and refuse to accept that they will have to bend. You will never get what you want so stop the BS. Speak specifically to systems and NOT with the intent to have them remove but how to improve the system. Stop trying to make the game in your image, instead accept the image larian has made but try to improve upon said vision.
It seems you are the one taking a hard stance here regarding fans of 5e or BG. And to use your rhetoric: Stop trying to get people to act the way you want. And asking for systems to be added, changed or removed is not futile in many cases. Look at Pathfinder: Kingmaker. Enough people asked for turn based combat, and they added it.
Regarding environmental effects: You deflected and ignored my points: 5e already has spells for environmental effects. Adding more will make it messy and unbalanced. 5e has balance issues at higher levels, adding lots of DoS elements to them will not make it better.
