See, also sysmon_envsys(9) uses this internally. If you want to do the
dubious and error-prone task of enumerating all powerd(8) users, you have to
go through all kernel configuration files on all architectures and all (MD
or MI) device drivers or other components that may use either sysmon_envsys(9)
or sysmon_pswitch(9). Then you have to maintain it.
I would say that the kernel does not need this kind of useless cruft.
Rather, we should make good default choices even if there is m68k.

I think the actual reason is: sysmon(4) was never really finished.
