Twitter is testing a 'soft block' feature

cover

Twitter has begun testing the first of its proposed suite of new privacy tools: the ability to remove a follower without blocking them. The remove follower feature is currently being tested on the web and seems to canonize the “soft block” concept as an official Twitter tool.

You will be able to remove followers from the follower list on your profile page. You just click the three-dot menu next to a follower’s name, click “Remove follower,” and your tweets will no longer automatically show up in their timeline.

This is different than blocking someone, which keeps them from viewing your tweets and direct messaging you (and keeps you from doing the same with them). Twitter’s new remove follower feature is more of a remote unfollow button, a gentler way to create some distance between you and someone else on Twitter.
