This is covered in the "Encoder" section: 

> An encoder converts a header list into a header block by emitting either an indexed or a literal representation for each header field in the list
...
References to the static table and literal representations do not require any dynamic state and never risk head-of-line blocking

I guess it doesn't specifically state the encoder "can always send" these representations, but I'm going for less=more here.  Maybe we can add it later, if really needed.  I don't think it belongs in Avoiding Blocked Insertions, since optimistic insertions could also be blocked, and have nothing to do with literal representations.
