Kunos at last commented on ACC modability, in short terms: No official mod support this time around.

We are totally aware of the importance of modding and its contribution to the success of Assetto Corsa.
It's a great way for new talents to emerge, for the community to "suggest" new directions and/or simply to make a product richer. It is not a coincidence that some of the best guys in this community are now contributing with us to the evolution of the software.
However, for ACC this element will have to be put in stand-by mode for a series of reasons. The most important one is that we have given ourselves an enormous task of rebuilding, once again our software from (almost) scratch. In a world where pretty much every product you see on the market in simracing is an evolution of games that have been on the market 10-15 years ago, our approach is to get a big axe and reset things to (almost) zero before starting with a new project, ACC is no exception.
In this case the task is rendered more complex by the fact that we are using, for the first time a third party engine that we did not design ourselves and the truth is, given the amount of time we have available to deliver ACC to the public, we have more than enough on our hands trying to figure out how to use the engine effectively to also think about how to make the platform moddable.
As you can imagine, this has been source of endless discussions in the last year and half as every decision comes with pros and cons, there is going to be pain no matter what your final call will be. It goes without saying that we believe we made the right call even if that means loosing the huge benefits of a moddable platform.
So to recap, there will be no action from our side regarding modding, both in the direction of promoting nor offering any kind of forum support for it as in the opposite direction, we have no intent to stop it from happening if some smart guy figure out how to do it.
