Middlewares added after a feature is instantiated do not get hooked into a feature's internal streams

This may be by design but it was not immediately obvious and drove me insane this morning. I was looking for the logging for an Actor in one of my Features but I was not getting any output. Turned out that a refactor recently had the side-effect of the Feature being instantiated before the LoggingMiddleware was added.

Is this a case that could be handled or if not, maybe it is worth calling attention to in the wiki.

Hi @kyhule , sorry for long reply times :)
It is intended by design to have middleware added before the feature.

The general idea is to create them before anything else is instantiated, and then use WrappingCondition and different selectors to determine whether to add middleware or not.
