There were mods minutes after Skyrim’s launch. Unless there’s a drastic change in how the games are set up, there are a set of mods that already exist that will work right out of the box if you install them manually. For instance, carry capacity. It’s just been a specific value on the player character (which uses the same ID for several years), so a mod for Skyrim or Fallout 4 or even Oblivion that increases carry capacity to 9999 will likely just work.
