I can buy the argument that it's nice to have some form of profiling

wonder if we could be investing effort into tooling around existing
solutions that will end up more powerful and flexible in the long run.
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) ;-)
