Why? What does this new view service offer that the existing one does not?

Ah -- I think you want to register some views, or override some views.
This doesn't entail replacing the Views service with your own one. This 
entails registering some custom widgets as views for some fields.

The views service remains the same. Its data is made up of a bunch of 
configurations which come from a number of packages.

That's ok.

Did I help?
