While I'd agree that having it like that would be nice for completeness,
it's:
- not necessary, as the button is not physically there, so the user will
never come into contact with it
- it will leak power, the plan is to park all unused pins after we get
"good enough" support for our devices (not now, so as not to mess with
ourselves in the dev process)
