Do you think translations fall under the concept of "porting" or "features"?

I'm already doing mental daydreaming over stuff I might want to do with my game this time, I don't usually have a lot of text or story in my jam games but I also am really curious to play around with setting up localization files (I also like dabbling in language learning, so translation into my target language(s) sounds like a fun mini-project on its own).

So if I set it up for localization but it only has English at launch, do you think updating the entry with other translations counts as a "new feature" (thus unacceptable addition post-jam) or "porting for accessibility" but for languages instead of consoles (where console/web/etc. ports are encouraged post jam)?
