Reclaim an Azure DevOps organization when it is not 'orphaned'

Question

This article describes the process of reclaiming an 'orphaned' Azure DevOps organization.

However, to be considered orphaned the organization must have no active administrators.

If your user is not a member of the organization, there appears to be no way to determine the members of the organization's Project Collection Administrators group (although there is a way to determine the organization owner).

Is there any way to reclaim an organization that is not orphaned, either because the owner is still active (but, say, unavailable) or because there are active (but unknown) users in the Project Collection Administrators group.
