Minecraft Resource Pack Language Changes

So about over two years ago it was possible to change the Text of some items and the menu text through .lang files. Then about 1.12 or 1.13 The files were changed to .json. I am not the biggest on things like coding but I was never able to change the text on items since then. I thought that there would be a change where you could again but 2 years have passed and it never added.  (At least that I know of) This was one of the best features in making resource packs and it was just gone. Do you have any other methods or plan on getting this feature back into the game please let me know. Thanks
