Remark 9.6.1.11. In the statement of Proposition 9.6.1.10, it is not necessary to assume that $W$ is closed under the formation of all $\kappa $-colimits in the $\infty $-category $\operatorname{Fun}( \Delta ^1, \operatorname{\mathcal{C}})$; it suffices to consider (levelwise) $\lambda $-sequential colimits for every infinite cardinal $\lambda < \kappa $.
