We had a great chat yesterday with Avi Kivity @ Scylla about seastar in

I don't think it's a good idea to start with the messenger since we
are currently making a lot of changes to implement the new V2 protocol.
This seastar messenger would only be used by the seastar-osd. The
existing messengers will still be used by everything else, so your work
there is valuable and shouldn't be impacted by the seastar project.
Whether a new messenger would want to target this v2 protocol from the
start (and ignore backward compatibility with v1 messengers) is an open
question.
