AFAIK, the intent of using pre-provisioned nodes is to create an overcloud
without power management control, among other things. Node import is not
required when Tripleo(Ironic) is not doing the provisioning.

I don't know if there are ways for Ironic to do power management of
pre-provisioned nodes. Someone else may have a better answer.
