Guys, Salph mod version has been submitted to them and they haven't torn it to shreads. I, along with most of my guild and many others, have been using it since day one and never had any issues. If you want to use one before they make an official announcement, this one is safe.
Its only FOV's offered in larger mod packs that include other illegal mods that will get you banned.
I do agree that the simplest option all around is to include the FOV mod of their choice into the files themselves and there wouldn't be any questions or confusion.
