I am referring to formalized standards here. There is exactly no literature that I care about which has been written in some English variant other than British or American. Why force students and professionals to buy special dictionaries and conform to oddball rules, which really only have a small number of differences, just because it tickles the fancy of a minority of would-be authorities. For example, Canada should just adopt American English. As for the countries mentioned in the article, the majority of "English speakers" there are not competent as speakers (easily seen by spending a few minutes reading Twitter), so the people proposing formalizing variants for those regions are not doing so in good faith, but to satisfy a political agenda that is only tangentially related to interest in language.
