Okay, for now, how about:

- If we're dealing with an existing spec, match the language.
- If we're dealing with a new spec, ask the authors to fix their language.
- If a new version of a spec has updated its language, adjust the kernel's.
- If we're doing with something "internal" to the kernel (including UAPI),
  stop adding new instances.
