Re: Anti roll back ...
Plus there aren't many of these "fuses" - normally only 16 or 32 bits.
Normally they are used for the device serial number and as markers for warranty-breaking events (eg overclocked, overtemp etc)
All they can is blow one more fuse each time.
So they're betting all their customers physical hardware on never needing more than 15 firmware updates.
Ever, on pain of total brick.
