Below is a copy of a forum post I found this morning on the BF3 PC forums. Apparently, to mod on the Frostbite engine, you need a LOT of different programs to optimize everything. Sounds complex to me

To my laymans eye it seems that there are a lot of build steps that are highly optimized and require a multitude of tools to support the build process. I'm not sure how you would get past the need for these tools in order to release mod tools.
Correct!
Building just a map requires jumping between ~20-30 different programs, and that doesn't even take into account the process of getting it into the game to test/play it, which requires the game source as everything is highly optimized and packaged for incredibly low loading times, despite the massive size of the map data and assets.
Everything, down to the way the game is compiled, is built and optimized for maximum performance.
