The committee still wants UTC to be periodically adjusted to match the Earth's rotation. They just want to adjust it less often, where "less often" probably rounds to "never" in practical terms.
Huh, so they want to go from small, frequent anomalies to large, infrequent anomalies. I think "never" is going to be exactly accurate; once we reach 1 minute of offset from astronomical time, everyone will be too afraid to adjust UTC because we'll have had a couple centuries of complacent software written in the meantime. Got it!
A leap minute once per ~century probably amortizes to a lot less effort. A leap minute is a bigger deal to implement, but you do it a lot less often. And the sun being off by up to a minute isn't a huge deal for humans
