I'll throw in my two cents from our experience, in case it helps.
We answered "yes" on that question on page 13, part 8 question 61 and have so far not received an RFIE or an RFE. We have simply received a notice of receipt, and soon after our online access codes.
However, that's all we received. No biometrics appointment notice as of yet and the myprogress simply says that it is taking longer than expected.
So, maybe there is some ground for the theory that cases with RFIE get processed quicker.
