Deletion of Lake numbers of Finland

Comment: I don't think it's a joke, but I have never heard of such numbering scheme, and it is not used at least by the Maanmittauslaitos|National Land Survery. Also, |Wikipedia is not a directory. As a sidenote, I can't help to wondering how many tax euros were wasted in making the jarviwiki.fi site – while it has elaborate structure http://www.jarviwiki.fi/wiki/Toiminnot:Tuoreet_muutokset it appears virtually unused
