That does a good job to explain HOW everything works. But doesn't
really cover whether a field should be made visible. The section on ""
just says to use it:

  "if it does not make sense for the feature to be exposed to userspace"

But that allows for the flimsiest of reasons to used to justify making a
flag visible.
