alt Hacker News> If one of your vendor blobs was specified for the old system and the new system is "similar", you'll just link it in and see what happens.
And what if that blob has instructions your new core just doesn't implement? This problem has nothing to do with overlap.
Then it crashes in a nice, obvious way as soon as you execute one of them? Illegal instructions aren't usually that hard to debug unless they're related to memory safety issues.
