That's the approach I am taking, and frankly I wouldn't cry if we just did away with the semantic difference and just had "never indexed".  While I don't think the extra bit will make a huge difference in compression ratio, it would simplify all implementations and it puts the onus of efficient encoding on the sender (vs. intermediaries like proxies).
