New Syntax for Custom Parameter postscriptFullName?

Hey! The custom parameter postscriptFullName called Full Name in the UI (till version 3151) seems to be written now (last update) postscriptFullNames with a final /s. Was wondering the reason of that change? And can I ask the reason why the postscriptFontName custom parameter is not affected by this as well? Thanks!

The full name can be localized. Adding the “s” means that it can contain more than one language.
Not to confuse with the postscriptFontName, that shouldn’t be localized. It is not visible to the user and acts as an identifier.

Ok! Thanks for clarification.
