Inspired by #1835 (comment) @joka921 we should discuss this. Technically requiring a sorted input is too strict of a requirement. In theory you could have an input that is not sorted, but as long as the same values are grouped together it doesn't matter.
We could automatically add a sort operation when the input is not sufficiently sorted, but there are many possible orders, and we run the risk of choosing a sort order that is suboptimal if we want to expand on the whole "keep sort order only when necessary" thing that is being introduced for
