Especially since it's fragile/unreliable.

Besides, even on traditional battery powered optics, changing a battery a few times per decade (or even once per year out of abundance of caution) is hardly an imposition. Barring perhaps those older types of optics that require you to unmount and remount/rezero the optic just to change the battery, which is thankfully quickly going the way of the dodo in newer optic generations.
