I personally wish the other way around: having Pytimechart merged in perf :)
If I remember correctly, the problem was that we don't have support for
trace_printk with perf?

But sure if more out of tree tools show up and want to use tracepoints,
we can think about librarizing it.

(Even though my secret hope is that
we build a nice one tool that can answer most tracing needs together rather
than many scattered ad hoc pieces.)
