So I really hope this SDT effort and the ktap effort at least make some effort in unifying all the nice functionality that's simple to use and easy to discover. I really, really would at the end of the day, just 'perf trace' like I 'perf stat' or 'perf record'.
Agree. I see user's eyes glaze over with each command line option, and we have added aliases to embed some of the details as well as having sensible defaults.
I often use perf-list to lookup an exact event name, and I do not want to see it taking many seconds to minutes to run (not everyone is running on an SSD). I also run perf on many different OS versions with an NFS home directory, and do not want to see a cache explosion (I have buildid disabled for this reason).
