I'm a software developer, and I've thought about my home router almost never. I've updated it exactly never. I'm using the default one from my ISP, and I think I'm paying a monthly rental fee for the privilege. I don't know how to tell whether my router is vulnerable, or what I could even do about it. If I'm not savvy enough for your proposed rules, which does seem quite possible, I don't think most people have much hope.
