Yep, for me this is one of the best things about the new lack of subscription. With the upcoming content pack/DLC functionality it should be even easier to set up moddable games.
Now it will be possible for devs to even ship a modified build with special editor tools and such. That’s amazing.
Modding is super important for longevity and to build a community, which are crucial for indie games anyway. Being able to support that in a seamless way is a huge benefit.
