It's a double edge sword. It make sense to pull them out before they break but if they are just about to break, they will break when you try to screw them out over those damaged threads.
And the whole key to success in extracting a broken stud is to be able to screw it in and remove the outer layers of thread. If you have started to unscrew a non broken stud and it seize and break on it's way out, you have just given yourself a lot more headache and even more careful planning is needed in how to use the extractor and if it makes sense trying to get it back in or force it back out.
Not a fun scenario at all.
When I'm in that area for a water pump or radiator and I notice it might be a loose stud. I give it a tug and see if it is possible to pull it out and put a new one in.
Sometimes, it is actually the stud that has worked its way loose and you can pull it out and install a new one. I would never try to reseat that loose stud and tighten the nut again.
