      By that logic every new URL parameter "adds extra attack surface". Collectors must properly escape data, same as other apps.

      By that logic all this CSP features "doesn't remove extra attack surface". Apps must properly escape data, same as other apps. ;)

      We can short-circuit this conversation by agreeing that a CSP violation reporting UI has to use CSP and send reports to itself ;)

      But really my point was that if a CSP collector doesn't properly escape data, then it's already boned regardless of `script-sample`.

          what you think our site is so innocent? You think we haven't used unsafe-eval, Joe so you know.

          Agreed. FWIW inquisitioners put lot of time finding ways to make violations explicable with an illustrative example.

          Automating the heuristic for choosing the right illustrative "sample" but is in some sense short & simple is hard but worthwhile.

          Interestingly enough *actual* integration with Inquisition might be in the cards as a tool to more easily debug CSP violations :)
