No experimental feature is cool enough to require you:<p><pre><code>  1. To register
  2. To Use an API key
  3. To detect support for (and presumably fallback)
  4. To provide feedback for
</code></pre>
You have a problem with burn-in of your experimental APIs? How about you semver your APIs and console.warn when it&#x27;s deprecated.<p>This problem has been solved many times before.
