Agreed. The motion/appeals process takes a long time so it's just not a realistic option for most people. Whether to withdraw and reapply or respond to the RFE will depend on your qualifications (apart from your acceptance into and participation in YC); we've taken both approaches when we've received a kitchen-sink RFE and obtained approvals doing both. The recent guidance focuses on the EB1A but an be applied to the O-1 and has expanded arguments that we can make.
