One of the primary focus of Micrsoft with the release of Dynamics 365 for Finance and Operations, Enterprise edition is to enable customers to easily uptake the enhancements and fixes Microsoft has done in the product. Extensions, model-split and hard sealing concept make that vision a reality. Microsoft is releasing, platform binary updates in monthly cadence, this means you can uptake new features and bug fixes, without breaking your code. Once application suite is hard sealed, you will probably get monthly binary releases for application suite as well. 

Now you do not have to go through expensive upgrade process to uptake these features. Specially if you in development phase, recommendation is to uptake these platform and application updates as soon as they are released so that you can utilize these new features when you Go Live.
