Moreover, I suggest CFF and CFF2 be removed from OFF. The claim-to-superiority of CFF format is: 1. better hinting, and 2. better compression. Re better-hinting, the interpretation of CFF hints is NOT specified anywhere. Adobe's code in FreeType is what we have. Re better compression, the existence of CFF in OpenType / OFF is partly why adding quadratic beziers to glyf table has continually not happened.

In reality, CFF only serves Adobe, who sells their rasterizer to MS / Apple platforms and serves only Adobe. Another example of Adobe abusing the "open" ideology / terminology is the Noto CJK / Adobe-equivalent. It's NOT open-source by any means. The sources are not available. That's something that I pointed out directly to Ken Lunde at one of his Unicode Conference presentations. Adobe is clearly aware of it. And I couldn't fix when I was at Google.

Rip the bandaid. Make open standards truly open.

With my SC29/WG3 member representative hat on (and _not_ serving in my capacity as a chair of this AHG) I object to this proposal. With many thousands of fonts currently deployed, and at least two (or more) different implementations available – this proposal, if considered, would do more harm than good.
