Quasidiagonality of extensions of quasidiagonal $C^*$-algebras

Let $I$, $A$, and $B$ be $C^*$-algebras in a short exact sequence

$$0\longrightarrow I\xrightarrow{\iota}A\xrightarrow{\pi}B\longrightarrow 0.$$

Assume that $I$ and $B$ are separable, nuclear, and quasidiagonal. Extension quasidiagonality conjecture. Then $A$ is quasidiagonal if and only if $A$ is stably finite. The question is a restricted form of the Blackadar–Kirchberg conjecture, motivated by the fact that extensions of quasidiagonal algebras need not be quasidiagonal without a stable finiteness condition. Its status is not resolved by the supplied source information.
