I suggest you to wait one more week to let other people comment the
PEP. After this delay, if you consider that the PEP is ready for
pronouncement, you can submit it to the Steering Council, right.
Note that the submission to the Steering Council doesn't have to be a request for immediate pronouncement - it's a notification that the PEP is mature enough for the Council to decide whether to appoint a Council member as BDFL-Delegate or to appoint someone else.
The decision on whether to wait for more questions is then up to the Council and/or the appointed BDFL-Delegate.
PEP 616 definitely looks mature enough for that step to me (and potentially even immediately accepted - it did get dissected pretty thoroughly, after all!)
Cheers,
Nick.
