Use of reducers on messages?

[jellea]

If I understand it correctly Messages are thrown away when they come from the channel and are directly being processed/mutated on to the app atom. Would it be interesting to take a more reactive approach here: keeping the messages instead and reduce over the messages to get the current state like in Elm? This gives a more flexible/reproducible history and allows you to for instance hot swap the processing protocols and see history change with it (like in the time travelling debugger). Planning to give it a try myself in the next coming days, but would love to have your ideas/opinion upfront.
