A filesystem abstracts out the access to raw disk... but under Linux we still allow raw access to /dev/sda TCP/IP abstracts out the access to the network... but under Linux we still allow creating raw packets. It is fine to have some sort of high-level abstraction of perf events for those who don't have PhDs in computer architecture. Fine. But don't get in the way of people who know what they are doing.
