Yes, they are still useful. Download managers can download specific range of files that we are only interested in which it can be filtered out. Like youtube-dl and gallery-dl, they are a specialized download manager and did amazing job with it. If I find a gallery of images that I like to keep. I can use gallery-dl for that and use gallery-dl "instagram.com/boburnham" in the command line and it will crawl and download the images within the gallery.
