Right, I see at least 2 actionable items:

* "The Checklist" which everyone making a syscall should
  follow and we create the checklist with input from both
  sides and it becomes the thing you reference e.g.
  "Did you follow the checklist? Where is X?"

* Programmatic / Machine readable description of syscalls.
  This way the kernel gives users the ability to autogenerate
  all the wrappers *if they want to* in a consistent way that
  matches this syscall description format.
