If the only user is the author, then I don’t see a meaningful distinction between shipped and not shipped. It’s like a blacksmith who said they invented a new tool with great value but they built it themselves and no one else is willing to use it because it’s so customized to their workflow.

Edit: I’ll add a caveat that I’d agree it was shipped if it’s making the author money even if they are the only user, but otherwise it all smells like dotcom era Pets.com level of selling a dollar for 99 cents and claiming it’s the future.
