Versioning update to Document Libraries in team sites in SharePoint Online and OneDrive for Business

While I can see the technical and support-focused rationale for making this change, I have to agree with the others here who have said that this is an overreach by Microsoft: it encroaches into an organization's ability to make business decisions regarding content management.

Fine, ensure versioning is turned on in new libraries by default and up the default number saved to 100.  But don't set the floor at 100, and don't restrict the ability to turn off version history to an API trigger.  This will hurt content managers' ability to configure according to business need, and would obscure the ability to understand the full configuration of an otherwise standard document library when examining its settings.
