Plugins are coming, and wrappers are still having to pay openAI and on top of that their own slice of the pie. Since wrappers aren't really cultivating the information themselves, nothing is stopping you from making your own either, the openAI API isn't a big difficult secret. You can even ask openAI to write your own integration for you!
You can probably also ask openAI about the nextjs/tailwind starter repo everyone of these wrappers keep relying on too.
