This is really useful, thank you. May I link to it from the fonts 
section of Formatting Information? I have a list there of those OTF/TTF 
faces for which LaTeX packages exist (so can be used immediately by a 
new XeLaTeX/LuaLaTeX user):

I believe fontforge is able to dump all the metadata from a font file, 
including character positions, Unicode code-points, names, aliases, etc, 
*without* dumping the glyph code itself, but I have so far failed to 
find documentation on the the incantation to do this.

You could also ask on TYPO-L (https://listserv.heanet.ie/typo-l.html)
