Can you create a master-switch deployment option? It would be similar to how this operates: https://sfswitch.herokuapp.com/

The issue is that this master switch does not always work with managed packages in production orgs.

So a way to automate the turning off/on of Validation Rules, Process Builders, Flows, and Triggers.

Use Case: We are building a new app and have significant data migration to do. It would help to have a master switch to turn off processes in PROD, deploy date, then, flip the master switch back to turning processes back on.
