Fake root with selective forwarding

Sorry to be thick here, but just verifying:

Assuming ForwardFirst and not root server.
1) If any forwarders are add to slist, then would NS delegation records even
be added to slist?  How about root hints?

2) If true, then for ForwardFirst: All forwarders are added to slist, any
delegations NS are added, and all root-hints are added.  So forwarders are
tried first, then delegations, then hints in that order?

3) If no forwarders are added to slist (either not configured or set to
"{}" ) then any delegations are added to slist if available and all
root-hints are added and tried in that order?

Thanks again Kevin.
