True, but that would lead to the same mess the Iranian calendar has, that you can’t calculate which year will be a leap year. This leads to fragmentation, lot of custom implementations of algorithms that are more or less accurate for the next hundred years.
You don’t need to adjust for calendar drift if you start the year on a soltice.
