<p dir="auto">I am trying to understand the real-world scenario in which this matters. I have an image running Sista bytecodes and my image format is 68533. I save an image segment to disk, and that image segment contains objects that contain compiled code that contain Sista bytecodes. The saved image segment records itself with format number 68021 (not 68533). Later on, someone loads that image segment using a VM that is a year or two old, so the VM does not know about 68533. But the VM probably does know how to run Sista bytecodes because it is only a year or two old. Everything still works, so as a practical matter what is the problem?</p>
