I think you misunderstand the goal of light markup languages like that. If you're interested in typography, you'd probably convert the markup to LaTeX. If you're interested in poetry or drama, you'd probably also convert to latex and use its packages. E.g. the (now dead) deplate converter works this way to allow markup of drama/scripts (e.g. http://deplate.sourceforge.net/Input.html#hd006005 http://deplate.sourceforge.net/Input.html#hd006005) etc. IMHO the main problem is that markdown, which serves its purpose well but isn't well thought out as a markup language because of too many ambiguities, dominates the "market".
