What do you imagine a standards board for English doing? Publishing an official standard and then everyone rejoices that finally someone has told them how to write the language they already write in? How is it any different from the myriad of 'rules' made up by well-intentioned people through history, many of which are now responsible for English's lack of well defined spelling rules?

In the end such a body would wind up either as descriptive, which is interesting academically but also useless from a standardization perspective, or prescriptive, which would just lead to it being happily ignored.
