Hello

Agreed to all these points and that is the long term objective of this.

Initially however, because we do not know exactly how the
api/interfaces will work yet, and will only allow the datapusher for
quicker development and faster iteration.

However, the whole point is to keep this extensibility in mind while
working on this so will will not find it difficult to add those
interfaces later.

Thanks

David
