OneDrive Sync to Support Sharepoint Document Management features
In order for Document Libraries synced from SharePoint to be available for Local Edit, effectively all SharePoint Document Management Library features must be switched off. The ODfB sync client should fully support the Content Approval, Check In/Out, Draft Item Security, Required Columns, Custom Views and Limited Lockdown Permissions features in SharePoint. It currently supports none of these and will make synced documents Read-Only if any of the above settings are used.
ODfB must support all of these features if it is to be described/considered as a compatible Sync solution.

Definitely a must. Users have to be forced to fill out mandatory columns when using ODFB sync just like the have to when using a web browser.
