According to Valve Anti-Cheat policy, Rust Radar should be legal?

The Valve Anti-Cheat page says:

"The Valve Anti-Cheat system is enabled for servers displaying the Secured shield logo. Using custom skins, sounds or maps and playing multi-player mods which do not modify core .EXE and .DLL files will not result in a VAC ban."

Rust Radar does not modify the Rust .EXE or .DLL files does it?

Rust radar gives players an unfair advantage.

Rust radar gives players an unfair advantage.

But according to Valve its legal.
Valve shouldn't be able to ban you on all VAC servers but instead let Facepunch decide what happens.
