I wonder why that didn’t happen on kick starter. Product hunt was kind of this. It’s actually interesting. Why didn’t this ever happen?

I think because you don't know /which/ developer you're going to get.

One interesting aspect of LLMs is that each one, weights frozen, can be thought of as a single developer whose work you have already evaluated.

The cost of finding, evaluating, and negotiating with a new human is tremenous.
