I have a 98 mauser action that came with a commercial 2 position safety for mounting a scope. The 2 position safety locks the bolt when safety is engaged not like the military 3-position flag safety that has a mid position that allows bolt to open. I like the bolt open feature and I can modify the tip of the 2 position safety to allow the bolt to open when safety is engaged either by grinding off a notch or even the complete tip. Is there anything wrong of doing it? It is pretty easy to do, but I don't think many has done it. Why? I cannot think of any occasion that I need to lock the bolt when safety is engaged. Why the safety is designed to lock the bolt when engaged? Commercial mauser side safeties do not do that!
