There seem to be two issues at stake here:

  * Is re-recognition a mainstream feature.  Not sure how we could come to agreement on this one outside a vote.

  * How much additional work in spec and implementation would be required for re-recognition.  I suspect if we can come to agreement on session tracking, re-recognition will look a lot like interpretation.

While there are use cases for this, I don't think that they are
important enough to warrant the increased complexity in managing
storage, references, and garbage collection of previously recorded
audio. Every feature that we ask browsers to implement makes it harder
for them to support our API.
