Indeed, the Imperium takes Psykers far more seriously than any other faction in the galaxy. (aside from Tau, since they literally have no Psykers, that we know of.) So yeah, even if it wasn't a full commissar, it'd at least be a commissar cadet so they get proper experience with 'restoring squad morale and ensuring true loyalty.'

The only way sounds about right. Why bother with fiddly little powers then you can fire endless streams of mindbullets? The only downside being potential for becoming an inside-out horror monster. Pushed is awesome for those moments where maximum power is needed - its even more funny when the psyker fails hilariously. But yeh, replacing is easier than repairing when it comes to the psykers - plus humanity is becoming more and more psychic.
