   * ## Canary Features
   *
   * EmberData allows users to test features that are implemented but not yet
   * available even in canary.
   *
   * Typically these features represent work that might introduce a new concept,
   * new API, change an API, or risk an unintended change in behavior to consuming
   * applications.
   *
   * Such features have their implementations guarded by a "feature flag", and the
   * flag is only activated once the core-data team is prepared to ship the work
   * in a canary release.
   *
   * ### Installing Canary
   *
   * To test a feature you MUST be using a canary build. Canary builds are published
   * to `npm` and can be installed using a precise tag (such as `ember-data@3.16.0-alpha.1`)
   * or by installing the latest dist-tag published to the `canary` channel using your javascript
   * package manager of choice. For instance with [pnpm](https://pnpm.io/)
  
    ```cli
    pnpm add ember-data@canary
    ```
   *
   * ### Activating a Canary Feature
   *
   * Once you have installed canary, feature-flags can be activated at build-time
   *
   * by setting an environment variable:
   *
   * ```cli
   * # Activate a single flag
   * EMBER_DATA_FEATURE_OVERRIDE=SOME_FLAG ember build
   *
   * # Activate multiple flags by separating with commas
   * EMBER_DATA_FEATURE_OVERRIDE=SOME_FLAG,OTHER_FLAG ember build
   *
   * # Activate all flags
   * EMBER_DATA_FEATURE_OVERRIDE=ENABLE_ALL_OPTIONAL ember build
   * ```
   *
   * or by setting the appropriate flag in your `ember-cli-build` file:
   *
   * ```ts
   * let app = new EmberApp(defaults, {
   *   emberData: {
   *     features: {
   *       SAMPLE_FEATURE_FLAG: false // utliize existing behavior, strip code for the new feature
   *       OTHER_FEATURE_FLAG: true // utilize this new feature, strip code for the older behavior
   *     }
   *   }
   * })
   * ```
   *
   * **The "off" branch of feature-flagged code is always stripped from production builds.**
   *
   * The list of available feature-flags is located [here](https://github.com/emberjs/data/tree/main/packages/build-config/src/virtual/canary-features.ts "List of EmberData FeatureFlags")
   *
   *
   * ### Preparing a Project to use a Canary Feature
   *
   * For most projects, simple version detection should be enough.
   * Using the provided version compatibility helpers from [embroider-macros](https://github.com/embroider-build/embroider/tree/main/packages/macros#readme)
   * the following can be done:
   *
   * ```js
   * if (macroCondition(dependencySatisfies('@ember-data/store', '5.0'))) {
   *   // do thing
   * }
   * ```
   *
