That's a very forced, contrived, un-impressive list. It reads like someone told them "hey, we want telemetry, please make up a list of uses that will sound plausible to programmers to justify it. Be sure to use big words like histogram a lot to shut down objections by sounding real smart."

Most of these things are in the category of bug prioritization. Why don't you... you know... talk to users?

If you want some statistics (oh sorry, histograms), maybe pull down the gigabytes and gigabytes of Go code residing on public repositories and places like GitHub and analyze all that. That'll tell you a ton about how people structure their projects, what architectures they target, etc.
