 /* Some things that are not currently tested that probably should be; this is

-   - Reporting event/beacon operation.
-
-   - Actually loading component ad --- see stuff in components-ads.https...
-     for examples.
-
-   - Check that topLevelSellerReportingURLs doesn't do anything in a component

-   - forDebugOnly diff between server_filtered or not (and also componentWin)?
-     forDebugOnly in general may be too hard to test given sampling. I should
-     probably ask Qingxin for his opinion.
+   - forDebugOnly --- it will be straightforward now, but will break.
+   - privateAggregation --- currently no away to test it, may be doable with
+     proper key config.
+   - Some of the parsing details that need to match the spec language exactly.
