If you ever need to extend that full page to do something else or something additional you might find the time not so different after all. Because you still don't know much about Typescript+React+React-Router-Dom+React-Hooks-Form and now you have to read that stuff and try to make sense of it, even if just for passing it back into the bot.

Actually writing code is a minority of my time spent developing software, I don't need to trade that for need to spend time to know what and more importantly why something is where it is.

I guess it does work if you just want it to generate a webpage and you never want to then add any functionality. Or a glorified boilerplate generator for stuff not on the prod path.
