Непонятно насколько добровольно-принудительны обновления, но c них станется стремиться накатывать автоматически и на D365O on-premises.
Dynamics 365 for Finance and Operations
Upcoming features (on-premises)
Dynamics 365 for Finance and Operations, Enterprise edition 7.3 for on-premises will be made available with the features listed below.
Deployment - Improvements to deployment will make setup and deployment more robust, along with automation to support most common topologies. For more information, see the most current setup instructions and troubleshooting guidance.
Servicing - The ability to apply Microsoft-released platform and application updates, as well as code customizations, to your environment post deployment through Lifecycle Services (LCS) for on-premises customers. This will enable customers to stay current with the latest set of fixes as well as take new customizations without having to reconfigure an existing environment or deploy a new on-premises environment. We will also add the ability to rollback code changes in case of failures during the package application. Note that the reconfigure feature will assist in immediately redeploying the on premises environment.
DIXF integrations - The ability to import and export data in data management via integration APIs will be made available for on-premises deployments. This functionality will enable you to integrate external applications with Dynamics 365 for Finance and Operations, Enterprise edition so you can import and export data using data entities.
Platform updates - We will also make the on-premises platform updates available at the same time as the cloud platform updates. Please review the software lifecycle for the currently available platform update for Dynamics 365 for Finance and Operations (on-premises) releases.
