I apologize for calling it snotty. Tone is hard to get right in email and forums (note to self: count to 10 before replying, excuse, don't accuse ...)
I got from that link that Kinook didn't think it a workable solution, but I don't know.
This Chrome page says using the tool suggested is "dangerous" and should only be used when "no other approach will work."

Could it be that Kinook doesn't think the risk is worth it?
