We do need to filter for 50hz/60hz noise. The EEG front-ends include what's called RLD which is used to cancel common mode noise.
But you are also correct we are currently only interested in the lower bands, mostly delta/theta/alpha, potentially beta when looking at wakefulness. We're not currently doing anything in gamma.
