My main complaint is that that's not user friendly *AT ALL*.

You need to make this useful to mere mortals: go through the
SDM, categorize interesting looking events, look at how it can
be expressed via tooling, add a generic event where appropriate,
provide examples, actually *USE* it to improve the kernel or an
app and see the workflow as it happens and improve the tooling,
etc.

Thanks,

Ingo
