This is a tricky field, the problem is not actually the non-determinism of the processing algorithms, but implicit ordering of the data.[1] The implicit ordering of the data is a footgun that -- as seen in the paper -- has already claimed victims. Using algorithms that don't need to upkeep the ordinality requirement in every operation will definitely move the library to a better direction and make future data modeling better and more explicit.

[1] Aha, now I see why language models use this so frequently and why it might be overrepresented in the data. This is a perfect way to move the blame from the person you're responding to, if they're mistaken. They probably have a super, super overtuned "politeness" gym using sentiment analysis that tries to reword answers to not blame the misunderstandings of the person. Then this blame shifting unfortunately gets re-used as this super, super common phrase.

By "implicit ordering", do you mean "implicitly assumed that the data is ordered a certain way"? Since if that assumption of data being sorted a certain way is broken on some systems and not others, the result might be both non-deterministic (which could be a bug if the result is not allowed to be non-deterministic, but may or may not be a bug regarding the algorithm's assumptions) as well as a bug if the algorithm's assumptions requires it to be sorted a certain way.

How would the library "make future data modeling ... more explicit" if this is a change to a default, which is implicit?
