> Should I restore that optimization in issue37319?

Yes, but to fix the bug it needs to occur earlier in the code (currently line 314):

    if stop is None and step is _ONE: <-- Line 314
                   ^^^^^^^^^^^^^^^^^  <-- Add this   

And again later:
         if istep == 1 and width > 0:   <-- Line 348
                     ^-- change to _ONE

As a standalone optimization, it wasn't worth it, but as a way to fix the bug without a regression, it is reasonable.
