You don't need the extra step. But for people who only know and use custodial lightning solutions, it's pretty cool and simple. I can appreciate the privacy add, too. I like the idea of a cheap "tumbler" between my purchase from Robosats and my node.
How don't I need an extra step? Am I missing something? Someone sends me nuts. I accept them. I then send them to my lightning node. Otherwise, they go right to my node.
Sorry, bad wording on my part. I meant it doesn't help you much since you run a node.
