I think they're kind of silly, but there's lots of stuff in the game I don't use/want. They don't impact gameplay, I'd let it go.
Now if they implement 10% greater top speed or 10% more ammo with completion of achievement X, there's something worth complaining about, and I'm gonna be snarly. Fortunately Hitech doesn't seem to be blindingly stupid, so I have faith that will not happen.
