Said an alternate way, if Kibana drop in compat could be a thing, it would be easier for infra teams to do it as a drop in into existing stacks at bigger companies which makes it easier to steal market share of existing customers on the ES stack. There’s probably a non trivial amount of existing dashboards built and UX familiarity that would be a friction point without seamless compat.

Is Kibana support totally out of the question?
