I'm not even going to bother to read those "common" BS stories, but technically you're not quite right. You can have a separate Apple ID for some of the stuff on your Apple devices (like App Store or Apple Music purchases), and another for iCloud. In fact, Apple forces you to do this if your original Apple ID is not an E-mail address. After they instituted that idiotic requirement, they refused to let you use a non-E-mail-address ID for iCloud.
