In some polls I've seen there's plurality support for "permanent 'summer time'". People don't seem to care much that noon in civil time maps exactly to the sun being at its peak.

Leap second drift is super slow, too -- IIRC something like 10 minutes per millennium. If we shift our clocks by an hour in the year 8000 I think that's less disruptive than leap seconds every year or so.

Keeping our clocks exactly aligned using leap seconds probably makes something like astronavigation easier

No, it's the other way around. Astronomical observation requires TAI, and leap seconds are cited as a navigational hazard.
