Just having a read of the boot loader documentation it becomes obvious that unless you deliberately program some of the bytes just above 0xffe0, someone could easily use the bootstrap Rx feature to download the MSP code, even after the JTAG fuse has been blown to protect the software. Unless you were aware of this, you would probably leave the area alone (unprogramed).
Someone attempting a reverse engineer of the code would easily guess that it might be 0xFF, 0xFF ... 0xFF, and still the code from the device.
