Counterpoint: this YouTube rant by an animation person called Noodle is a pretty good overview of why frame interpolation sucks. https://www.youtube.com/watch?v=_KRb_qV9P4g

Basically, low FPS can be a stylistic choice, and making up new frames at playback time often completely butchers some of the nuances present in good animation.

Low FPS can be a stylistic choice, but as a member of the audience, I tend to disagree with that choice.

Perhaps it depends on the quality of the execution, but there are shows where I wished I had frame interpolation.

Personally I'm dubious. There may be times when the low framerate is a stylistic choice, but the vast majority of the time it's purely a budget thing.

Which the style is then centered around.

If it had looked better with frame interpolation the studio could have baked it in, before release.

If you are a good director you can make the most of that low budget. Look at the first episodes of Scum's wish (https://www.imdb.com/title/tt6197170/) if you want a good example.
