Serge responded quickly to my email, suggesting this query:

He also said that the CFML Plugin project contains only old issues, so you need to apply those criteria to the Everything context. I created a new context from that, called CFML Open Issues, which I can see, but my guess is that other people can't. You can do that yourself though, so it's one click away.
