I mean, everyone knows that it is I the microcode somewhere. If something glitched then it's possible that it would unlock even if it wasn't stable. (Like how some x3 phenoms would do x4 and some wouldn't) If the owner does a BIOS dump and we can analyze the microcode then someone smart should be able to find the difference and exploit it.
Even though not all chips (or even most) would be able to unlock it would become a handy tool. Some i5s might become 4c/5t because only 1ht core works, or maybe some unlock an extra bit of cache. Some i3s might even unlock extra real cores, but that would be rare as they are usually really defective.
All in all, this shouldn't be passed off as a impossible chip, even if it is. There is so much we could do with this.
