The mirrors inside the template represent a database that I want to be in a certain state. Template instances should reflect the current state of that database. But during the use of a template instance I need to change the mirrored items because of how I’m using each instance. However I don’t want those changes to affect the original database.
This feature would allow me to deploy template instances in the image of the current state of the database, change the instance as needed, and still maintain the state of my OG database.
