That's too bad. I was hoping you would be able to adapt the proposal to
implement a dynamically allocated matrix. I should hope you can still take
advantage of SIMD optimizations with dynamically allocated memory. Plus,
move-friendly data structures are (or can be) a Good Thing.

I stand by my statement that there's value in that effort. It may be
unlikely to see review for another year or so, but it shouldn't invalidate
the work.
