Istio dependencies / minimal install

OpenShift says that Jaeger and Kiali are hard dependencies, but when I read through, I don’t see any indications that these are necessary to install istio. Earlier versions of openshift seemed to be capable of installing without Jaeger - which is what I’d like to do, since thats very resource intensive, and I’d like to get started with a low footprint. What does a minimal install of istio look like, and where are its dependencies / pre-reqs documented?
