Earlier this year there was a 'preview' option to allow for the Compare and Deploy features to interact with Salesforce Marketing Cloud orgs and business units. That option has gone away and I would love to have it back. As we support both CRM and Marketing Cloud it would be a great option to fold our Marketing Cloud configuration into our overall DevOps, especially around sending MC configuration and metadata to Github and different branches of a repository. In addition, it was going to be very helpful for moving configuration and metadata between different Business Units within a MC org as well. So, I would like to request that Marketing Cloud come back as a source and destination option in metadata deployment options to better incorporate MC into Salesforce DevOps processes.
