Which doesn't mean there are no boards using it. But EOL in 2010
might be a strong argument to remove it. But I don't see the need
for it, yet.

So how would you test newer versions of this series?

That's true, but we need it to detect flashes during runtime in the
future. Imagine sometime later, there's a third flash with this
exact ID, then we need to have the SFDP to figure out if there are
any differences between yours and the new one.
