title: VSCode: Is it possible to suppress experimental decorator warnings
body: <p>In VSCode, I get the error:</p>
  <blockquote>
  <p>&quot;Experimental support for decorators is a feature that is subject to change in a future release. Specify '<code>--experimentalDecorators</code>' to remove this warning.&quot;</p>
  </blockquote>
  <p>I can add the <code>--experimentalDecorators</code> flag to my <code>tasks.json</code> file to remove this error on build, but I can't seem to remove it from my intellisense or error list when I load VSCode.</p>
  <p>Is there a way to do this?</p>
