I believe that is what the Lodestone article is sharing about.

Guess they would be priortizing on upgrading and changing the in-game UI.
Pretty sure they already know what are the popular ones being used, I think some others have opened threads to showcase the third party UIs.

My ultimate guess is that they want to ensure that the console players won't lose out in terms of UI usability.
Currently, the console players do not have the ability to tap into these tools to modify their UI like the way PC players do.
