Multiplicity equality conjecture for elliptic A-parameters

Let $G$ be a unitary group or an even orthogonal group, and let

$$\psi=\sum_i \phi_i\boxtimes S_{d_i}$$

be an elliptic $A$-parameter for $G$. Let $\pi$ be an irreducible representation of $G(\mathbb A)$ such that the $L$-parameter of $\pi_v$ is $\phi_{\psi_v}$ for almost all places $v$. Multiplicity equality conjecture. The discrete multiplicity of $\pi$ equals its predicted multiplicity:

$$m_{\operatorname{disc}}(\pi)=m(\pi).$$

This conjecture is formulated to extend the paper's multiplicity formula from generic elliptic $A$-parameters to all elliptic $A$-parameters, by implying equality in J.-S. Li's inequality. The supplied passage does not state whether it has been proved or remains open.
