What is the kind of person who would use such software? What you’re describing is the need for a two sided market where really only one side exists.

A user would have to be someone who doesn’t have access to an LLM to make bespoke software themselves, and isn’t able to use existing software. I think that’s a vanishingly small segment of people.

Sounds like the user could just ammend the software to his need with the LLM, but instead of sending that update to the maintainer with a pull request, just keep it to himself, to the users version.

You're assuming that everybody will be equally skilled in using an LLM to create software. I don't think anything in my experience indicates that this is true.
