Since the big operators are vertically centered by TeX with respect to
the math axis, the relative proportions of the height and depth are
normally not important. I would guess that the height values used were
an expedient forced by the Metafont limit of 15 heights and depths per
.tfm file. This hypothesis seems to be supported by the use of the
padded operator in bigop.mf for the displaystyle versions.
