So your argument isn’t that Apple should rush one release but have two big feature updates every year? Am I understanding this correctly?
Not necessarily 2 updates a year. For instance in 2016 there was only 1 update for Windows 10. Roll out features as they become ready. For instance they are planning an overhaul of the home screen in iOS 13 which is probably only one aspect of the entire update. Break up the update into parts instead of releasing it all in one go. No need to fix a month in which it should be ready
