Baldwin's categoricity conjecture for atomic classes

Let $T$ be a countable first-order theory and let $K_T$ be its class of atomic models. Baldwin's conjecture. If $K_T$ is categorical in $\beth_1$, then $K_T$ is $\beth_0$-stable, equivalently absolutely categorical. This asks whether categoricity in the first uncountable cardinal forces the strongest stability behavior for the atomic class; the source presents it as an unresolved question.
