I'd vote for rejecting images that have auto-resize set when the MTD is read-only. In fact, using UBI on top of a read-only MTD is very uncommon and not recommended (for NAND). The auto-resize flag should be also only set when you just have created it using mkfs.ubifs. Why would you inspect such an image with the kernel UBIFS unless you're hunting down a bug in mkfs.ubifs?
