The 4000 year exception is a proposal by people who are trying to
bring the mean year closer to their target tropical year. But the
Gregorian calendar is meant to follow not the tropical year, but the
northward equinox year, and that adjustment makes it less, not more
accurate. Additionally, adding another adjustment like that increases
the jitter of the calendar, thus lessening the value of such an
adjustment.
