The whole point of my [P3122R0](https://wg21.link/p3122r0) paper is that I think implementations should make their own decisions about where to use nodiscard. The standard should do no more than make some vague recommendations, and definitely *not* try to standardize where it should be used (or even worse, standardize where it should not be used).

So I am very pleased to see this change and the start of a discussion. Please don't wait for WG21 to specify nodiscard on individual functions or on some minimal "low effort" set of functions.
