Why wouldn't I use this? I've built enough validation sites like this that I bought a React boilerplate project. From there changing the text and deploying to Heroku or Vercel takes me an hour or two.

I like the idea but I'd get worried about using something that's not extensible. I don't want to have to shoot down ideas on website improvements from the non technical folks strictly because I'm limited by the framework I used. Just me though.
