Why for `AbstractMessageChannel`s just don't use their **bean name**? 
I may be a bit confused when I'll take a look into headers before/after (de)serialization. And to understand 'where I am', I have to use `ReplyChannelRegistry#channelNameToChannel`. Right? 
From other side it may be interest from which `Thread` the `TemporaryReplyChannel` came
WDYT?
