In my opinion there should be a MUST include one and only one CRL. Then offending MFTs can be considered broken, and there is no defensive code needed.

I don't see how this could be an issue for CAs given that none include more than one CRL on MFTs until now. But if other CA implementers disagree then I would be very happy to hear about it.
