People should stop using the Photos app. It is an application designed to lock you in first, make your life hard second, and manage your photos a far third. If photos are important to you, you should never ever put the master copies in an opaquely-managed proprietary container. It prevents you from auditing your files easily, it also prevents you from making backups in other media. Photos isn't even useful; leaving the photos as files allows you to pick multiple tools to manage them better.
