While I agree with the logic of this naming scheme, I'm afraid that
the glyph names in existing AFM files aren't always systematic, not 
to mention that some glpyhs are named by meaning rather than form, 
i.e. "suchthat" rather than "epsiloninv" (actually "epsilonrot") 
or even "nabla" instead of "Deltainv". It is certainly possible to
introduce a consistent naming scheme in our .etx and .mtx files, 
but that doesn't solve all problems.

Cheers, Ulrik.


P.S. On a different subject:  I happened to notice that a new draft
of the HTML-Math working group has been released in early January,
one chapter of which also discusses entitiy names. As usual, you 
can find it at   http://www.w3.org/TR/WD-math/
