Can you explain what this is needed for?

What is the problem if it's used to detect cheaters? It's the server problem if it lead to a fake ban.

You can already do this with

print(GetConvar("profile_vidScreenType", 1))

oh ok good to know but very few people know it adding the native would make it “easier”.

Because this will lead to servers trying to force players to play in "Fullscreen" or risk being banned because of the possibility of the player cheating.

There is also no need for the server to have access to this information, unless you have another reason other than "to detect cheats"

A set screen type of Windowed or Fullscreen (with a non-default resolution) would result in this returning false. So there's no way to differentiate between a non-focused game window and these screen settings. I can't think of any use case where a script could benefit from this information.
