Swim smooth has an interesting pair of videos that makes the argument that minimizing strokes per length isn't the same thing as maximizing efficiency. Janet Evans and Laure Manaudou are cited as examples of swimmers with high strokes per length and a faster turnover. Elite triathletes with shorter strokes are also cited. The idea is not to advocate everyone use a shorter stroke but just to say that if a shorter stroke works for you don't throw that away in pursuit of lower strokes per length.
I wonder if swimming with a shorter stroke and higher turnover is analogous to using a lower gear when cycling (spinning versus grinding). People generally acknowledge that the optimal gear to use will vary from individual to individual. Extrapolating from that line of reasoning, perhaps elite swimmers using longer strokes do so because they have greater strength/more power that allows them to use a longer stroke/higher gear rather than because they worked on lengthening their strokes (although the two are clearly related).

The videos are fascinating. Thanks to the OP for posting.
I am suspicious that hand size, or more correctly the
cross-sectional area of the hands and forearms is closely
related to stroke count; smaller hands => more strokes.
To support this hypothesis, I note that with hand paddles
stroke count often goes down. If you have small hands
you simply have to condition yourself to be able to
maintain a higher stroke count if you want to swim fast.
