Seems fair enough to me - personally I want to play Planetside2, but with everyone on the same client, no mods to do this or that.
Even texture and model mods shouldn't be allowed unless every player has that same mod, server side mods might be the only fair way. I mean, say I'm allowed to edit textures and gun models and even FOV - I change the enemy textures to bright day-glo orange so I can see them easily, I change the gun to nothing but a crosshair (for no-scope shots), I change the FOV levels to expand my normal view, and increase my zoom view. Those are unfair advantages before even considering an external program mod.
Mods and hacks just annoy me... I played WarZ the other day, spawned and instantly got shot up, managed to slither away when 'whoever' got distracted by some Z's - then in pitch darkness a hacker starts sniping me in the next village. PVP in general is ruining WarZ, take away PVP, take away the desire to hack, and it'd be a better experience. We already have DayZ, a straightforward co-op survival game would be nice... trying to kill people by luring Z's to them would be hilarious.
