You will face the same license limitation as if using web forms.
With that said, Kentico 8 MVC is mainly customized development. You cannot use any of the webparts or widgets anyways. So the limitations with regards to components is not relevant because you'll have to build it anyways. So the limitation mostly has to do with interacting with the CMSDesk such as creating User roles, # of administrators/editors, # of documents, # of custom tables, etc.
