Not for all persons but for some of us it's still necessary. I've published 726 articles with 5 more coming out this coming week. Even though I have the vast majority of those in Lists, some of the lists in Lists were too long to scroll through. So I created multiple publications by genre and moved a lot of my work into those. The publication format makes it a lot easier for readers to scroll and see (almost) everything at once as opposed to the "See More" or whatever it is at the bottom of the profile.
