Temporarily declaring bankruptcy on the *desktop* system health benchmark.
The number of alerts became unmanageable and the overall process needs to be improved to make it sustainable.
The alerts have been turned off and I'm archiving the outstanding regressions.
Note: this is just about desktop, the mobile system health stays up.
