Well, a bootloader and the self-detection was useful for the bootloader self-update. The update bootloader would be copied in a different section and on reset would start and copy itself over the original bootloader section.
I also wanted to maintain full functionality even at shifted location in case the self-copy process somehow failed. Never did fail, at least to my knowledge.
