Currently only ArcGIS Online users with the default administrator role can create a tracker view and manage the the list of tracked users/track viewers. While security concerns are understandable, for some organizations this can make Track Viewer cumbersome to configure and maintain.
Making tracker view management an administrative privilege that can optionally be enabled for custom roles would allow other users to maintain tracker views without having full access to all the administrative configurations of the organization (similar to the administrative privilege to create/manage shared update groups).
