Of course similar modifications could be applied to the regular
LaTeX definition.  Ordinary LaTeX shows even more clearly how the
enlargement of the arrowheads messed up macro packages.  (It also
shows the error of freezing macro definitions "for stability".)

There were many years when the pure metafont CM had the enlarged
arrows, but the bluesky outline fonts had the original shapes, so
the worst overlaps weren't generally seen until more recently.

That is a standard macro.  Or do you mean I omitted a use of it?

Good to know.
