I’ve had to ship the draft a few times in my career. Usually when the actual code would have been weeks or months more of work (draft has poor architecture, while a proper architecture would have been just as much work as the draft). Twice it was due to showing a demo and a decision maker in the audience said “we can sell this tomorrow” or something to the same effect for that org. In one case, we ran a simple a/b test as a proof of concept on whether to pursue the idea further and it added an extra million bucks a year in revenue. Nobody wanted to wait for a proper implementation. All that code is still in production, slow as shit and nobody wants to fix something that isn’t broken.

If you have a draft, keep it to yourself. Use it as a personal reference when writing the design, or share snippets. Other engineers will realize you have a draft, business people won’t.
