The bleeder screws seize up because they aren't often used as in bleeding the brakes, and the rubber boot that keeps water out is missing or torn. If you are concerned about breaking off the bleeder screw or stripping the threads then remove them, clean and apply never-seize or a little grease, and bleed the brakes. When done replace if needed the rubber boots because when water gets in and the brake calipers get hot they will get stuck eventually. If the threads in the calipers do get stripped a good machine shop can repair them and for a lot less than replacing them. I know White Post can reesleeve them so I guess they can also repair a stripped bleeder screw hole.
