Explicit scripting is completely unsupported at this time, only UnityEvents. Complete alternate gamemodes are far off, unless modders can get really creative. The Infinite Arena modder used a plugin called UltEvents to better utilize the UnityEvent system, so it can be decently robust but it's a much higher barrier to entry and it can only go so far. Any complex implementation is going to be very hacky.
Further mods to the engine are likely extremely unsupported, though I do imagine when scripting support launches they will give us access to the physics. Showing modders the moonbase level and not giving us gravity controls (or at least not fucking documenting it) NTRd a lot of modders.
