Parâmetro de rota opcional do Laravel no meio do URL

No. Optional parameters need to go to the end of the route,
otherwise Router would not know how to match URLs to routes.
What you implemented already is the correct way of doing that:

get('things/entities', 'MyController@doSomething');
get('things/{id}/entities', 'MyController@doSomething');
