Depends on what @markfisher thinks but we can open it up to just `Codec`. Only problem really is that we don't have "springy" ways to configure Reactor components in general. They're really designed to be created in Java code (e.g. JavaConfig) using a fluent, DSL style. That means always writing wrappers and other bits of glue just to use it from XML. Wish there was an easier way to go about it that didn't involve all this middleman stuff that has to be maintained...
