This is why there is a power button. I suggest that you go to your PC and yank the power cord. Whether it is running Linux or Windows, I suspect it won't like it.
If you can't use the power button, then yes you can design a cape that will let it gracefully shutdown properly. When I designed the board I felt that a button was less expensive that all the other stuff you would need to put on the cape. Not to mention the small form factor of the board made it tough to fit all that onto the board. And yes, in a small number of instances, we have seen that yanking the power may cause damage to the processor because the PMIC does not have enough time to power down the processor in the correct voltage sequence. So, use the power button.
