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) ;-)
