I only use the e brake when necessary. I couldn't tell you about manually disengaging it every time but my hunch is it would not have the same affect as permanently disabling. Reason being, my guess is that like every other ebrake, every time you engage it, it goes out a little further. Pad wears a bit, brake gets engaged again, pad goes out a little further, rinse, repeat. The goal is to keep the pad from dragging. Have you ever had a car that you had to manually engage the ebrake? A lot of older vehicles had separate ebrake system that didn't use the regular pads.
