They are biased towards new users of a codebase, not only the language. Named arguments improve readability of a code if you are not used to a codebase. By improving readability, you also improve maintanability: you need less experience in a codebase to make a change. You focus on writability where it's not the biggest issue of the field, it's software debt.
