It horrifies me personally to think about doing anything of this sort, i.e. having markup to specify en-us and en-gb spellings. What a waste of energy, if you ask me.
Jimmy... out of everyone here, you should know best that Wikipedia isn't about what you or anyone thinks is a waste a time, but what people *actually* waste their time on.
If people are willing to spend some time using this syntax to specify both spellings, why not let them? It might seem like a little thing to many if not most people, but it would certainly give Wikipedia's content a more professional and consistent overall appearance.
