> Because such long words would certainly be split up between their constituent words, not between random places. At least for German, this is not a requirement. Hyphenation doesn't happen at random places but at syllable boundaries. The only care that you should place up hyphenation is that it shouldn't lead to possible misreadings. "Ur-in-stinkt" being the classic example. Only split that word at the first, never at the second possible hyphen.
