(as an individual contributor)
I like this much better than your earlier proposal that required special 
handling in the decoder, since it doesn't require any changes to 
already-deployed decoders, and keeps the decoding process (relatively) 
simple.

A few minor points:
- The start of the Encoder Guidelines section should forward-reference 
the LPC Extrapolation section.
- Need a reference on how to actually compute the linear prediction 
coefficients. We have references to both the Burg method and the Schur 
algorithm in RFC 6716, and source code in libvorbis. Some implementation 
guidance wouldn't be amiss.
- The language in general needs a little word-smithing. We can 
coordinate on that in git.
