It's just occurred to me that you might be inclined to disagree (probably not, though), because English is a weird language that tends to torture itself by trying to follow the correct pluralization for words of Latin and Greek origin... But I think no other language? I mean, at some point you have to realize the futility of that. Because almost no language has completely regular plurals, so you'd have to become an expert in the language of every borrowing.

In contrast, Russian has been happily "domesticating" all kinds of borrowings, among which "jeans" which has become "jeansy" (with our own plural ending tacked on) and "chips" ("chipsy").
