Weld is the reference implementation of CDI (Java EE standard) and it's integrated into WildFly. WildFly 8.2 contains Weld 2.2.x which implements CDI 1.2. The "featured" version you're talking about is the version of CDI API, not Weld. Actually, the CDI API is the only dependency you need to develop a portable CDI application. Weld 3.x is not a stable version - it contains prototypes of changes currently being discussed by the CDI expert group for the upcoming CDI 2.0.
