I imagine that this will happen organically if Luxury Yacht ever grows to the point that I can't maintain it alone anymore. Although given that it's such a niche thing, with a relatively limited scope (relative to your Linux comparison) I don't really see this happening.

The more likely outcome is that something happens to me and I can't maintain it anymore. But if there's sufficient interest in keeping it going, anyone can fork it and pick up where I left off.
