All very good points. I think it would look silly, but sure, it’s possible. However, I think Apple would only choose it if the version after 10.9 didn’t look all too different from 10.9. If they did some kind of UI overhaul, it would be a good time to jump to a new major version – maybe even ‘OS XI’ or ‘OS 11’.
