What is the intended type for this callback? Would it related to the Mojo
interfaces at
https://cs.chromium.org/chromium/src/components/chrome_cleaner/public/interfa...
?

With the current design we won't be needing all that information. At the moment
I'm thinking of
bool scanSuccessful
vector<string> uws_names

+void RegisterUserInitiatedSwReporterScan(base::Closure callback);
+
 }  // namespace component_updater
