Well, for TrueType fonts it's probably not that important. First of
all, it is possible to have TT fonts without a `post' table, this is,
without glyph names. Second, glyph names in TTs are often
non-standard (consider infamous issues like `Ohm' vs. `Omega').
Only glyph names in OpenType fonts based on CFF and CID are worth to
support, I think.
