Regarding concerns about Wikilawyering, I don't think it's wikilawyering if one follows the underlying spirit of a rule/guideline/etc. rather than simply following it to a letter. Wikipedia is intended to be a tertiary source, reflecting what other people wrote. Generally guidelines on naming order/etc. are meant to have Wikipedia reflect the practices of published English-language literature. Having Wikipedia's policies on a person's naming order determined by the policies of reliable sources would fulfill the goal of making Wikipedia a tertiary source.
