By WanWizard:

Before diving into the if, check if Request::active() exists though, it doesn't have to be.

I tested with

if (class_exists('Request', false) and $request = \Request::active())
{
$paths = array_merge($request->get_paths(), $paths);
}

and that works perfectly, but I couldn't think of something clever to use as cache_id.
