</div>It's hard to evaluate a proposal that doesn't actually do anything by<br>
itself. I don't see any problems in principle with this approach, but<br>
it's impossible to say for sure without a full proposal. It could be<br>
that this approach forces problems in other parts of the design which<br>
aren't evident yet.<br>

</div>How does Chrome figure this out at present? Does it include hardcoded<br>
heuristics like checking the RTT to <a href="http://google.com" target="_blank">google.com</a> itself? Does it<br>
optimistically assume that the feature should be used, so fetch the<br>
page, then discard it if the page somehow says not to use it?<br>
Something else?<br></blockquote><div><br></div><meta charset="utf-8"><div>The app has the heuristics. The UA fetches the page and discards it if the page doesn't indicate support. As pointed out this is suboptimal. Perhaps we need a two phase indication of support. First OpenSearch indicates that the page might support it, then the page itself has a chance to deny support on a per-request basis.</div>

</div>Feedback from other search vendors would be particularly essential<br>
before this becomes standardized, I'd think. Possibly other search<br>
engines would have somewhat different takes that would require a<br>
different API.<br></blockquote><div><br></div><div>Agreed. That is exactly what I'm trying to elicit. </div></div><br>
