I get what you're saying, but is this really as fragile as you claim? I've been rather impressed by (GPT) input handling.
If anything, this is "less clever" than older techniques like tree-search, as it is very easy to confuse, and will start just producing nonsense.
Or, seen another way, it just has to be smarter than most peoples' web frameworks, or perhaps their IDEs, which is not a very high bar.

I guess you could create some kind of UI prototyping app, but better options for that already exist, which don't require you to write everything out.
However, while these systems based on GPT-3, and similar techniques, can produce some amazing outputs given the right inputs, you don't have to poke them very hard before they start falling apart.
At the end of the day, this isn't really any more "clever" than a very, very advanced and long markov chain, there isn't any intelligence.
