yes, but you are taking abstraction to the extreme.

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.
