We saw few ID collisions even between flashes of the same manufacturer, macronix.
Reusing flash IDs without providing an extended ID field, or ignoring the
continuation codes is bad design, and I would avoid using such flash. But I won't
reject new flash additions solely because they have a wrong identification mechanism.
We'll cast an indirect public shame on the collisions by writing hackish code when
trying to differentiate between the flashes in software.
