AFAIK most of that info is in HN and twitter discussions between webappsec people. Here's a link[0] to a CSP leak that was briefly discussed on the webappsec mailing list. I also know Homakov wrote one[1].

That's one of the reasons I like this talk so much. It really cemented these type of issue with real attacks, instead of a loosely described bunch of PoC. I remember reading somewhere on an RFC (perhaps CSP) that reporting can cause unwanted information leakage, but I didn't find it in the security considerations with a quick control+f just now.
