News to me, but apparently so: https://www.bipm.org/en/-/resolution-cgpm-27-4

(This sounds like kicking the can down the road to me; making the maximum discrepancy a minute could take 50-100 years and then you need a leap-minute or equivalent).

No. But the Earth has sped up a bit, so they're less necessary than at some times in the past. And we're on schedule to change them to be some kind of bigger, yet-undecided adjustment (perhaps a whole minute) before the year 2035 comes to a close.

If we move to leap-minutes, the Earth will do whatever it does, and it is expected that we'll be able to run on atomic time for a period of decades or perhaps even a century before we need to make another adjustment like we've done with leap seconds in the past.
