I would be surprised to find out that non-units strides are relatively
common (say, above 0.1%) outside of several specialized fields, like
linear algebra and image processing.

There are yet other fields where we can encounter increments that are
non-constant throughout duration of the loop. Bart would probably say
that such loops do not count, in both senses. I.e. they are not
counting loops, but forms of while loop.
