My approach on the tracers/rtla is to make the simple things in kernel, and beautify things in user-space.
You could keep the tracepoint as a mask, and then make it pretty, like cpus=3-5,8 in user-space. For example with a trace-cmd/perf loadable plugin, libtracefs helper.
For rtla I was thinking to make a new tool to parse them. and make it pretty there.
