This new feature is promising but I've noticed a few possible issues.

1. When a name isn't originally written in Roman script (Chinese, Thai, Hindi, Arabic, etc.), and that's entered into the name field, it isn't showing up anywhere even when the default language is set to that language. It only appears when it's copied over and duplicated on the "translated" name field of the original language, something you shouldn't do (which makes sense and follows the rules for movie and TV names). For example, see this profile and switch over to the Japanese translation or set your default language to Japanese temporarily: https://www.themoviedb.org/person/110665. The kanji name is nowhere to be seen and the EN translation is featured. Edit: No longer applicable. The updated contribution bible makes it clear that the main/stage name must be in English.
   
   
2. The name in the local script needs to be shown somewhere when viewing the profile in a different language (much like a movie or TV entry that always shows the original name in the sidebar). It has to be easily viewable for all users so those who can't read the name in the local script, so can confirm they have selected the correct profile. Until that happens, the original name should probably be left in the list of additional names, otherwise, I'd bet more wrong crew data will be added for non-English entries, and probably more duplicate profiles created.
   • An example of where the current behaviour will be a problem/hassle: Risa Suzuki (鈴木理彩) vs Risa Suzuki (鈴木理沙). You can see the romanized names of these people are identical and they both work as animators on Japanese productions, but their kanji names are different. Currently, the kanji name is listed in the alternative name section, but if it's removed, then the only way to check would be look at the changelog as far as I can see. Edit: The updated contribution bible's guidelines has also been made clearer now: “The name in non-Roman script should always be added as an alternative name.”
     
     
3. Finally, there are many locked main name fields which means only mods can update them. That seems like a big hassle.
