Comment (by joehoyle):

 @danielbachhuber I don't think we should do it in an automatic way, if I
 wanted to add support for a query var, I'd do this:

 {{{#!php
 <?php
 add_action( 'rest_post_collection_params', function( $params ) {
         $params['date_month'] => array(
                 'type'        => 'integer',
                 'description' => 'Restrict posts to ones published in a
 specific month.'
         );
         return $params;
 } );

 add_filter( 'rest_post_query', function( $query_vars, $request ) ) {
         if ( $request['date_month'] ) {
                 $query_vars['month'] = $request['date_month'];
         }
         return $query_vars;
 }, 10, 2 );
 }}}
