Should we be defaulting to true?

I'd rather put this through a few more tests. It can be overridden in the config map if necessary.

Why was this added? Do we directly depend on this property anywhere?

Yes, right below. The deletion events apparently had a status without a container id.

std::placeholders::_N leaves me a bit puzzled. Is there a way of doing these methods without using unbound arguments?

They confuse me too. Unfortunately, there is no better way.
If it helps, think about std::bind as: you have to list all of the arguments to the bound function, but some of those can represent the arguments to the function being called -- that's what placeholders are (std::placeholders::_1 is the first argument to the resulting function).
