Even use-cases where you have different objects whose differences are ignored for __eq__ and __hash__ and you want to grab the one from the set ignoring their differences would benefit from this.
A more concrete use case might help make the argument better. My first thought was a function that needs the zero value for a set of (ints, floats, polynomials, whatever) could just do elements[0], but how often does that come up? (And how often can you trust that the type’s zero value is ==0, but can’t trust that the nullary constructor returns a zero?) I’m pretty sure I have run into a handful of more useful uses for this method over the years, but I can’t remember any. Maybe something to do with Unicode normalization?
