> Kind of, but differences in time will forever deviate from the SI second so I don't think that really counts.
I don't follow. Outside of days with a leap second, you are using the SI second.
If you're measuring skew via raw-seconds-since-epoch or something similar, that's already an error-prone measurement. It's a non-goal for smeared UTC to be synchronized with TAI, just as it's a non-goal for unsmeared UTC to be synchronized with TAI.
