Does it exist? Or is it just a theoretical concept?

Yes, it would work fine if all our users were perfect. Let's continue with
the same example and imagine what Catgory:Finland would become like.
10.000 images, maybe? Then we have this dufus (see
http://commons.wikimedia.org/wiki/Commons:Welcome_log) who uploads an
image with only [[Category:Finland]]. That image will be lost forever. No
one will ever find it and no one will ever be able to use.

Thanks to what we have now, that wasn't the fate of these images:
