I use it for storage because I can stream a recording, with full seeking, while I'm actively capturing it, or I can stream it over a websocket for a little less latency. Having one thing that works just as well as WebSockets as it does over HLS makes things a lot easier on low performance devices where a format conversion would be a bad thing. MPEG-TS is like a virtual analog RCA jack, it's easy to understand and work with and manipulate as long as you don't have to touch the encoding or decoding stuff, and lets you do lots of odd applications.
