BAC has a large collection of modding from the community combined with overlap (or inclusion?) from self sufficiency
https://www.unrealworld.fi/forums/index.php?topic=7176.0IIRC Rain had done iron working and Rain's self sufficiency if thats that you mean by "self sufficiency", or was it Endive? Been a while since running the original "self sufficiency". If so alot of rain's work has been included. Due to the numerous vanilla updates the old Rain's iron and SS won't run or not fully compatible. BAC and other mega mods exist in part to update Rain's work and combine them with others.
By concept though BAC does give you access to many trades and skills to be self sufficient, like making your own axes and weaving clothes.

edit: Bouidda also did self sufficiency type mods with much rolled into BAC
