Unlike the old EWS the new EWS system does not comment on bugs when a failure occurs. As a result of this lack of bug commenting => there is a lack of bug emails => a person must manually poll each of their bugs to know if the EWS found a problem. Different EWS bots take different lengths of time to process a patch plus patches could be sitting in queues waiting to be processed. Polling for EWS status either is inefficient and wastes many man-hours. (This includes implicit polling by way of leaving the browser window open and glancing at the bubbles every so often). We should add some mechanism (maybe an opt-in registration) for people that want notifications about EWS failures to receive them. Concrete example, I posted a patch for bug #199960 a week ago, forgot about it and thought the reviewers forgot about it. Went to go check that bug today to find that the patch failed on the ios-wk2 EWS bot. Some reviewers are naturally hesitant to review patches that caused EWS failures (there's a lot of reasons why). If I had known days ago about this failure then I would have updated the patch and may have already got it reviewed and landed.

It would also be cool to be able to opt-in to receive notification on patch failures for bugs **I am interested in**. Old EWS supported this by way of Bugzilla bug mail settings.
