Fabric API is by far the most popular dependency, with 8 config libraries using it: ConfigToolKit, Configurable, Fzzy Config, MidnightLib, MonkeyLib538, oωo, QoMC, and YetAnotherConfigLib. The rest of the dependencies are one-offs: Fabric Language Kotlin (used by Fzzy Config), MaLiLib (used by MaLiLib API), UI Lib (used by YAML Config), Mod Menu (note: as a required dependency) (used by McQoy), YetAnotherConfigLib (used by McQoy), and lastly adventure-platform-mod (used by MonkeyLib538).
