Hmmm, kind of a dangerous assumption to make. Stuff I've worked with have
the flash chips programmed before PCB assembly, and yes, you can re-flash
the chips including the "boot blocks" via software, possibly rendering the

Not in the case above, unless you call harware guys with SMD rework
equipment "Developers" ;-) Sometimes it is easier|cheaper to replace a
whole PCB than to provide the ability to re-flash a chip on it. It is even
done deliberately in some cases.
