What if we drop leap seconds completely, but for display and input, we use continuous interpolation, with factors published every year, a year in advance(So that mostly offline devices stay accurate) Imaginary civil days would always have exactly 3600×24 seconds. We could always convert any past date easily with a small table. We could convert any future date with reasonable accuracy just based on extrapolation. No ambiguity, no jumps, we still stay roughly in sync. We could even just use 10 year blocks so that in the short term, most projects would have the entire future conversion factor timeline known at the start.
