 * I think it is related to this
 * Seal can verify that packages installed during development are identical to those
   installed during deployment. The standard npm shrinkwrap only ensures that package
   versions are the same, but does not verify contents. seal checks the shasum of
   the package tarballs downloaded by npm during development and deployment to ensure
   they are the same.

 * if I remember correctly, seal.js was a 3rd party js thingie used to display a
   page’s SSL certificate status on thy fly. it needed to excluded because at the
   time AO moved non-aggregated JS around (it still can, but does not by default
   any more) and it did a document.write or so.
 * that being said, you can safely remove it, I just left it in there as an example
   🙂
