So, let's summarize:
- sysmon_pswitch(9) can still be used to register power switch events,
these events being modeled following a "switch" functionality e.g. when
a threshold is passed.
- pmf(9) is focused on device states, so it's lower level than
sysmon_pswitch(9) events. pmf(9) event injection is not supposed to be
called directly, but rather through sysmon (for switch-like
functionality), or within pmf(9) itself for inter-device signaling.
So, in the current form, power switches/buttons are not supposed to
register as devices and implement their own hooks for registration with
