Just a clarification for leddbate: Forking, in a programming context, is the practice of taking an existing codebase and building atop it in a way that diverges from the efforts of the rest of the code. By forking a codebase, the original set of code continues down it's own development path (you can think of this as one tine of a fork) while the forked copy goes down another (For reference, these 'tines' are usually called branches). This means the skse team isn't, from your description, saying no one else can make a script extender, just that they don't want them using existing skse code to do it. There are a number of reasons for this policy, but from a modding perspective the most compelling is that it would diverge the modding base into skse and forked branch groups, reducing overall MOD intercompatibility in the long run. It also means that the final version can be updated with confidence instead of being stained by reports actually stemming from the forked branch, facilitating maintenance, troubleshooting, and confidence in the final product. And because I haven't said it before - thanks, behippo and team. I and the skyrim modding community eagerly await the fruits of your labor.
