There hasn't been much change in the format, so we can consider the feature stable and start being careful about breaking the format. (This is somewhat of a pre-requisite for anyone actually using the feature in the real world and depending on it) Drop the experimental note and the warning text about the on-flash format not being finalized.

Instead of scanning the whole MTD device it only has to locate a checkpoint (called fastmap) on the device.
