Remark 9.2.2.8. Let $\operatorname{\mathcal{C}}$ be an $\infty $-category and let $W$ be a collection of morphisms of $\operatorname{\mathcal{C}}$ which is closed under transfinite composition. Combining Examples 9.2.2.4 and 9.2.2.7, we deduce that $W$ contains every isomorphism of $\operatorname{\mathcal{C}}$.
