I would suggest that this material be fleshed out quite a lot with usage
scenarios, applications, etc. Something which will help the kernel team at
large understand the *value* of this work: what it offers our users.
Because people generally don't know that stuff yet. And if one starts
explaining all this complexity, bug-potentiality and overhead-potentiality
to kernel developers without first making it very clear what it will be
gaining us, they will revolt.
IOW: do not presume that people want *any* of this stuff at this stage.
First up, they need to get all fired up about how cool it all will be ;)
