The enhanced Shahidi conjecture for generic members of local Arthur packets

Let $G$ be a quasi-split reductive group. A local Arthur packet is a packet of representations attached to a local Arthur parameter, and it is tempered when its parameter has no non-tempered Arthur factor.

Enhanced Shahidi Conjecture. For any quasi-split reductive group $G$, a local Arthur packet is tempered if and only if it has a generic member.

The source says this conjecture is proved assuming the preceding wavefront-set conjecture, and unconditionally for some symplectic and split odd special orthogonal groups. It remains open in the generality stated in the supplied text.
