Leap minutes are not, realistically, going to happen. The proposed bound on DUTC is something like 100s, and that bound is not fixed. The reason for keeping a bound is to appease those who don’t want to give up on it, but in practice once leap seconds have been abolished the bound will be extended not enforced.
Leap seconds are just to be replaced by a yet to be defined adjustment, likely leap minutes.
If you don't like leap seconds and don't care about a small (but increasing) deviation from Earth's angle you can do so today: Just use TAI.
