The unitary dual conjecture for general connected reductive groups

Let $F$ be a non-Archimedean local field of characteristic zero, and let $G$ be a general connected reductive group defined over $F$. Let $\Pi_A(G)$ denote the set of Arthur representations, and let $\Pi_{\overline{A}}^{\lim}(G)$ be the set obtained from them by unitary parabolic induction, complementary series, and limits of complementary series. Assume that the local Arthur conjecture holds for every Levi subgroup $M$ of $G$. Unitary dual conjecture. The two sets are equal:

$$\Pi_{\overline{A}}^{\lim}(G)=\Pi_u(G).$$

This conjecture seeks to construct the entire unitary dual from Arthur representations using the standard unitary constructions; its resolution is not established by the supplied text.
