ftrace global trace_pipe_raw

I am doing correlation of linux sched events, following all tasks between cpus,
and one thing that would be really convenient would be to have a global
trace_pipe_raw, in addition to the per-cpu ones, with already sorted events.
I would imagine the core functionality is already available, since trace_pipe
in the tracing directory already shows all events regardless of CPU, and so
it would be a matter of doing the same for trace_pipe_raw.
But is there a good reason why trace_pipe_raw is available only per-cpu?
Would work in the direction of adding a global trace_pipe_raw be considered
