Changes (by jonsurrell):

 * severity:  normal => minor


Comment:

 `modulepreload` is only added for static module dependencies.

 Modules dependencies like the following will not have a `modulepreload`
 added (assuming it's not a static import anywhere else in the dependency
 graph):

 {{{
 #!php
 $deps = array(
   array( 'id' => 'my-module', 'import' => 'dynamic' ),
 );
 }}}

 Dynamic dependencies would still benefit from dns-prefetch.

 These dns-prefetches are also added early to the page. On non-block
 themes, all of the script module tags are printed in the footer so there
 may also be an opportunity for dns-prefetch to happen before any of the
 module related tags are processed.
