It would be nice if I could composer require wp-less from a plugin or theme folder as a way of installing wp-less.
Currently due to the "type": "wordpress-plugin" if you try this wp-less will end up in /wp-content/themes/{yourtheme}/wp-content/plugins/wp-less and wp-less' dependencies will be put in /wp-content/themes/{yourtheme}/vendor. wp-less.php is not designed for this structure as it expects that either it's a plugin or that the vendor folder is relative to it.
