 We'd only have to add it to metrics-web, and it would save us half a day
 of writing code and testing it. After all, we also rely on libraries for
 things like base64 encoding, which is not rocket science to implement
 ourselves. We wouldn't have to add it to the metrics-web .war file!

 Related aspect: When we rewrite the censorship detector (#21588), we'll
 have to compute mean and standard deviation of approximately 50 sample
 values. We'll probably want to use a library for that, too.
