 Using permalink, I suppose that all query_var entered manually on URL or
 using $_GET will be redirected to proper permalink. Apparently not all
 being redirected at all. AFAIC:

 1. /?post_format=image : should be redirected to /type/image/
 2. /?pagename=blog : should be redirected to /blog/
 3. /?author_name=admin : should be redirected to /author/admin/

 Unfortunately, they are not.

 It can be done by filtering redirect_canonical() but it will be better  if
 it's being done by default as we can see that /?category_name=cat will be
 redirected to /category/cat/
