 WP_Query meta_query numeric value results in comparison to a string value

 1.
 {{{#!php
 <?php
 function intercept_query_clauses( $pieces )
 {
         var_dump( $pieces );
         return $pieces;
 }
 add_filter( 'posts_where', 'intercept_query_clauses', 1, 1 );
 $query_args = [
         'meta_query' => [[
                 'key'     => 'key',
                 'value'   => 10,
                 'compare' => "="

         ]]
         , 'fields' => 'ids'

 ];
 $query = new WP_Query( $query_args );
 }}}


 result:

 **AND (
   ( wp_postmeta.meta_key = 'key' AND ''wp_postmeta.meta_value = '10''' )
 ) AND wp_posts.post_type = 'post' AND (wp_posts.post_status = 'publish' OR
 wp_posts.post_status = 'private')**

 2. using 'type' => numeric results in
 **AND (
   ( wp_postmeta.meta_key = 'key' AND ''CAST(wp_postmeta.meta_value AS
 SIGNED)'' = '10' )
 ) AND wp_posts.post_type = 'post' AND (wp_posts.post_status = 'publish' OR
 wp_posts.post_status = 'private')"**

 which doesn't solve the problem + why casting the field and not the value?

 Am I missing something big here?

 Thanks
