It was important for us to treat Eve (at least initially) as the whole world, because part of our task was understanding the implications of building programs in this different fashion. Datalog applications have a rich design space for tooling, and after 3 years poking around in the space we barely scratched the surface. The interoperability between a datalog world and the current state of things is another great research question, and one we made some good progress on this front with v0.4, but there was still much left to do in the end.
Has there been any discussion about open-sourcing Eve? It's a shame to see the project abandoned without at least making it available for other people to try to maintain. It may not find the right set of maintainers, but if the project shuts down without putting the code out there, it will definitely die in darkness.
