How is the Olson database fundamentally different than the historical data that a future historian would have based on the measurements of the delta between what we call today TAI and UT1 times? It is just more data for them to swizzle into their calculations?
Because a mean solar clock is automatically a stable subdivision of the calendar - stable over long periods of time as well as geographically. Noon on two different days is separated by an integral number of days no matter what period of time separates the two dates and how the length of day may have varied in the interim.
There is no swizzling needed if civil timekeeping remains tied to the Sun.
