Strictly outer actions satisfy the Intermediate Subfactor Property

Let $G$ be a locally compact group and let $Q$ be a factor, with an action $G\curvearrowright Q$. The action is strictly outer when it is outer on every nontrivial subgroup in the sense used in the paper.

Strictly outer action conjecture. Any strictly outer action $G\curvearrowright Q$ on a factor of any type satisfies the Intermediate Subfactor Property.

This conjecture generalizes the paper's intermediate-subfactor theorem beyond the semi-finite setting and beyond the specific hypotheses treated there. Its status is not determined by the supplied text.
