Exactly: that was one other thing I found artificial.
Surely the points will then be wanted as arrays.
So my view is that we still do not have a use case
for wanting matrices yielded when iterating across
rows of a matrix.
PS In the "large number of points" case, the thing to
do would be to extract modest sized submatrices.
