 Replying to [comment:101 enricocarraro]:
 > You can safely remove `unsafe-inline` from the CSP header on pages on
 which every piece of JavaScript is included via a nonced script tag.

 All of the sites I manage use Varnish or similar caching for non-logged in
 users.  For example, WP Engine calls it "full page caching" I believe.

 It's unclear to me what will happen when the nonce is cached in such a
 situation.
