You're wrong. This is a case where whatever you're comfortable with is the best solution. Just because you personally don't know frameworks, or js frontends, doesn't mean the people who do are inferior or less secure. I guarantee someone who knows how to work a framework can turn out the same work much more quickly and more maintainable than someone who is working from Vanilla PHP and having to implement basic logins and email templates on their own. And a "throwaway project" can also be turned into something customer facing much more quickly as well. I agree, you don't need to pick bleeding edge tech, but you should pick something stable and well documented and run with it rather than basically having to rewrite the same project in the framework once you've got it up and running in vanilla PHP.
