Thanks for the update, much appreciated.
I see no mention of If-* headers and cannot recall there being reason provided to omit them (on-list, at least). Certainly being able to make conditional requests that would otherwise be allowed as non-conditional should be allowed?

They are allowed. Though even for GET requests they would require a preflight request first. Currently the only headers that are allowed without preflight (only GET requests can go without a preflight) are Accept and Accept-Language, based on earlier feedback from Ian Hickson. However, maybe we should simply remove those and always require a preflight request for a request with "custom" headers. Not sure.

I think it's useful to have a white-list of headers that should be safe for GET requests without a pre-flight request. I would actually like to expand the list a little. There was a thread on that a while ago, but it seemed to have died without reaching a useful list.
