The issue AFAICT is that running perf is done by $YOU, the specialist,
whereas the performance framework put into place here can be
"turned on for the whole fleet" and the ability to collect data from
non-specialists is there. (Note: At GitHub you do the serving side,
whereas Google, MS also control the shipped binary on the client
side; asking a random engineer to run perf on their Git thing only
helps their special case and is unstructured; what helps is colorful
dashboards aggregating all the results from all the people).
So it really is "works everywhere," but not as you envisioned
(cross platform vs more machines) ;-)
