On these chips the encryption and integrity checking feature is one and the same you can't turn on one without the other.
Whether or not you use the same key over every device in a product line or a per device key is up to the oem. So you can still verify firmware in the former instance.
Replacing the FPGA chip is a lot harder than re-flashing an eeprom and they would also have to put a lot of effort in to replicating your firmware just to insert their change.
