The armor and weapons community had the same problem adding items to the crafting workbenches so the Armor and Weapons Keywords Community Resource (AWKCR) was also created.
The settlement mod building community came up with the Settlement Keywords* framework in an attempt to standardize and improve on the vanilla workshop menu structure. Since keywords are the key component in making workshop menus this meant that additions to the workshop menu in mods was a serious problem. Well Bethesda didn't learn that lesson and in the beginning Fallout 4 had a ridiculously small keyword limit. In the beginning the quote '640 K ought to be enough for anybody' was misattributed to Bill Gaits regarding computer memory.
