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
