Comment (by keesiemeijer):

 Yes, it could be used with `trim()`, but you still have to use the
 `PREG_SPLIT_NO_EMPTY` flag otherwise it returns a non empty array for
 empty strings.

 {{{#!php
 <?php
 $list = preg_split( '/[\s,]+/', trim( $list ), -1, PREG_SPLIT_NO_EMPTY );
 }}}

 The `parse_wp_list()` function is there so you can get values from comma-
 or space-separated lists without the sanitation from
 `wp_parse_slug_list()` or `wp_parse_id_list`.
