New firmware can change all sorts of things, but I think firmware_rev is
the only exported sysfs attribute we expect to change. Other attributes,
like model, serial and unique id's, should be stable across these types
of firmware upgrades. I don't think "activation without reset" can be
used for firmware upgrades that change fundamental ways the device
operates.
