[MPEG-OTSPEC] Introducing breaking changes into the spec (was: RE: [EXTERNAL] Proposal to deprecate derived search values)

[Roderick Sheeter]

I see the hackers path as wide open! Font compiler and rendering stack are
open source, we can (and IMHO should) play with implementation as early as
we like without regard for business cases and spec changes. Q

We just have to remember if we want other people to implement we need to do
our due diligence at some point and get the spec updated.
