There is a bit of a fine line between caring about the future and not screwing them over, versus just being so arrogant as to think we know now the right thing to do for them.

But given the amount of time it is going to take to accumulate so much as another leap minute's worth of leap time, let alone an hour, I'm pretty confident we're in the "arrogant" branch if we start declaring what they need.

P(nobody cares about UTC anymore anyhow | someone had to solve the problem of incorporating non-terrestrial time which is way harder than leap seconds) would seem to me to approach 100%. You can decide which branch you want to take, but P(things just keep on keeping on without much change from today for the next several thousand years) seems not large enough to start trying to make lots of plans for.
