Yeah, as far as I can tell Beth wanted to "get away" with giving PS4 users access to mods that use external assets. That would've been a good thing: it would've allowed you to download some great mods.
When it comes to mods Beth are a forward thinking dev, they want people to have access to as many mods as possible. Beth.net had hundreds of FO4 PS4 mods which used external assets, they were all removed after the announcement that the PS4 wouldn't get mods. I imagine now they will slowly start showing again but due to Sony those mods will be more limited.
