I know some people disagree in various degrees. At the same time, the parts of the consensus rules verification that depends on storage has not been encapsulated out to libbitcoinconsensus yet, and I agree that changing the database is unnecessarily risky at this point. Even when the consensus rules are encapsulated, that doesn't mean that Bitcoin Core should be DB agnostic or that we can guarantee that it will follow the longest valid chain with databases that have not been tested.
