Comment:

 The patch I attached contains a solution. Like @dan.rossiter said, it's
 the best solution that doesn't involve refactoring how mime types are
 handled. This won't change anything unless plugin/theme developers obey
 the new $ignore_user flag. It works like this:

 {{{#!php
 add_filter( 'upload_mimes', 'user_mimes', 10, 2 );

 function user_mimes( $mimes, $user_id, $ignore_user ) {
         $mime_types = array( 'test' => 'text/test' );

         $user = get_userdata( $user_id );
         if ( $ignore_user ) {
                 $mimes = array_merge( $mimes, $mime_types );
         }
         else if ( $user && $user->user_firstname === 'Abe' ) {
                 $mimes = array_merge( $mimes, $mime_types );
         }

         return $mimes;
 }
 }}}

 Basically developers would need to return all of the mime types their code
 adds if the $ignore_user flag is true.
