FYI that feature isn’t the same as defederation, not by a long shot:
Users can now block instances. Similar to community blocks, it means that any posts from communities which are hosted on that instance are hidden. However the block doesn’t affect users from the blocked instance, their posts and comments can still be seen normally in other communities.
It’s only really for communities on the Instance. So if the issue is something like Hexbear’s spam or harassment, a problem with users of a particular instance then this feature won’t help. So it’s still important to consider whether instances have defederated in these cases,
With Lemmy 0.19, you can block instances individually FYI.
