*   Tensorflow code now produces 2 different pip packages: `tensorflow_core`
    containing all the code (in the future it will contain only the private
    implementation) and `tensorflow` which is a virtual pip package doing
    forwarding to `tensorflow_core` (and in the future will contain only the
    public API of tensorflow). We don't expect this to be breaking, unless you
    were importing directly from the implementation.

  - `spec.usages` is now required, may not contain duplicate values, and must only contain known usages
  - `status.conditions` may not contain duplicate types
  - `status.conditions[*].status` is now required
