Hiding language input fields based on role

[Beluga]

How can we show only the default language field for a certain role and hide the rest of the input options? I'm thinking PageTitleLanguage specifically.

There's no build-in mechanism to do what you want I guess. The easiest route I see is with AdminCustomFiles. 

I would install that module, check the checkbox for config data.

Then build your logic with the config.AdminCustomFiles object.
