I didn't mean that. I found FreeType 2.8 can load it without hinting, but 
current head would load it with or without. 
FreeType 2.8 is "happier", but not happy.

 in (older?) versions of the `glyphs'

 remove the `prep' and `fpgm'

 if you want to create a font without hinting.  

You mean https://www.glyphsapp.com/  ? It is reputable, but libre fonts being 
manipulated/maintained by proprietary app feels strange....

 those tables probably works with Windows
 – it seems that executing
 `prep' and
 `fpgm' gets only triggered by the first glyph that
 contains
 bytecode – but not with FreeType,
 which executes those two tables
 unconditionally if hinting is requested.
 
That might be a long-term change to make?
