Philip,
In your text, you write:

This may be true for geometrical shapes used in a mathematical context, but
might not be universally the case.

thank you for your reply -- point taken
re-reading N4115, I see that the "...scaling of geometric shapes should be
harmonized with rules used in TR25...", with no mention of vertical positioning
however, some of the Webdings/Wingdings shapes are shown in N4115 as unified
with existing shapes, which do (or should) obey the positioning rules of UTR
25
so, in order to maintain the horizontal alignment of (some of the other)
Webdings/Wingdings geometric shapes, they, too, will inevitably have to be
vertically centred on the math axis
