The '-ize' prefix is official International English - OED English. No partisanship (for example) necessary (in fact, '-ize' in OED is a Graecism, not, say, an Americanism).
Trying anyway to link the idea to the context: there is no need to translate a Local Language work into an International Language transposition - no need already per se. But especially, it is most normal for works of arts to written using specific localisms, well in a deliberate concept from the author - it is normally the duty of a translator to try and convey those choices, which makes it below absurd to suppose to instead nullify those features in a standardized relative of the same language.
