I disagree there; the sysmon API already defines register functions for
events; you are supposed to register them first before posting them to
powerd.

Granted, the current registering operation is a NOP; but I think these
functions were introduced for one good reason, and here it is: if you
don't have any sort of event registered when powerd(8) starts, you
shouldn't expect it to handle some in a "stateless" manner later.
