<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I've got two problems with this.
The first, and easy to fix, is that messages are supposed to be immutable. That's what allows them to be shared across threads without locking. If we think this should be a part of the base message type, I would ditch the setter, add a stasis_message_create_with_eid, in which you specify the EID. The stasis_message_create can still fill it in with the default.
Secondly is whether this is really needed at all. I can only see this being applicable for a small set of the messages that Stasis will deal with; most cases won't care at all. Given that, I would say that if a specific message needs an EID, then it should be a part of that message itself.</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">It only matters for messages that are distributed which are/will be MWI and device state changes. I'll move it into the message data.</pre>
