Yes and connect them to ground or similar just to ensure that those legs
are hard to do things with. I'm just worried that they do stuff with
internally or do tempest leakage that we don't know. It is just harder
to audit with a lot of cruft.

We should definitely go over the CPU we select and try to kill off
everything we don't plan to use. Esp external signals.
