I have attached a picture to show you what people actually see on a 4 X 3 resolution and on a 16 X 9 resolution from movies and you can apply this to videogames as well.
The exact same scene on a 4 X 3 resolution will enable you to see more vertically than horizontally.
The exact same scene on a 16 X 9 resolution will enable you to see more horizontally than vertically.
This means that a specific moment in time, someone could be seeing stuff that the other person would not see.
Scenario 1:
In scenario number 1, in the top image where you see Gandalf from Lord of the Rings knocking on the door with his stick.
You can clearly see that on the 16 X 9 resolution (Wide screen), we can see the following details that do not appear in the 4 X 3 resolution (Full screen):
-A small bench on the left side of the screen
-A tree on the left side of the screen
-A lantern on the left side of the screen
-A complete view of the tree on the right side of the screen
You can clearly see that on the 4 X 3 resolution (Full screen), we can see the following details that do not appear in the 16 X 9 resolution (Wide screen):
-Details of the upper side of the house on the top of the screen
-A complete view of Gandalf's pointy hat on the top of the screen
-The first step leading to the house at the bottom of the screen
-A complete view of the grass at the bottom of the screen
All of that to say that even though adding a
"widescreen option" to the game was "up-to-technological-standards" for 2018, we still broke somehow the old mechanics of the game with that first major change ; meaning at some point in time during the games, some people will see stuff that other people are not seeing.
Now you are adding another game breaking factor which is a
"zoomed out" perspective of view (Camera height) which would also mean that some people might be seeing even more stuff that other people are not seeing.
So with those 2 major changes, you have created (intentionally or unintentionally) a very big gap between what some people might be able to see on screen and what others might not be able to see.
Those two major changes have a considerable psychological impact on the way you get surprised or the way you plan your attack and defenses.
In my opinion, a widescreen option is really where you should have drawn the line before you brake the game mechanics even further by playing with the camera height.
If it was for me, I wouldn't have even added a "widescreen option" and would have kept it the way it was for the past 15 years.
