I’ve had a chance to briefly chat with @Daniel, the proposal author, who is currently unavailable. He agreed to move this proposal to the next phase and label it with an SEP number.
Meaning, we have our second SEP now! 
According to our governance process, this proposal needs remain here unchanged and open for feedback for at least six days from now.
From previous comments and the lack of change requests, the proposal seems quite mature. Let’s see if further changes will be proposed over the next six days, if not it could be uploaded to Snapshot.
