I just was establishing my perspective.
And yes, verbose code is not readable either. A balance must be found.

The one which allows the user to create multidimensional slices. From

I'm generally satisfied to use a function instead. But passing a slice
of a sequence to a function that manipulates it, creates copies.
I think vertical slicing could provide a noticable speed gain.
Pulling a 1st level column from a dimmed sequence is quite common.
