As an partial answer to Stefan Hennig's comment: There are (existing and documented in the typographical literature)
situations where no hyphenation is worse than some hyphenation. In german typesetting this applies to \emph{Rauhsatz}
which is a kind of flushleft-raggedright typesetting. Because german words tend to be long, hyphenation at preferred 
hyphenation points is much better than no hyphenation at all.
