in the past I had machines that after enabling powerd brought the machine
down needing a full power cycle to restore. this had always been
machines in production unfornately where pople had forgotten to do so
during install and thus almost impossible to debug.

I am fine with having this on by default for "install" (whatever that
means) but changing that policy with a system update mergemastering
might not be a good idea.
