Questions on the new feature and migration covered by bug 19476483 "PROPAGATE POWER FLOW RESULTS ACROSS A MODEL SPLIT "

Q1)  What does this imply for where PF_SOURCES are defined?

Q2)  Should they be defined only for the upstream sources, or for SRC nodes at both the upstream sources and model break sources?

Q3)  If PF_SOURCES are not defined at the model break SRC nodes, does it imply that the angle, voltage and impedance are propagated from the upstream sources?
  If this is the case, does it imply that there is a performance impact as I'm guessing that PFService is solving a larger island?

Q4) and question regarding this statement "To continue to achieve full functionality from FLISR, Suggested Switch and Volt/Var it is recommended that the splits be above the substation power transformers."
  What functionality is lost if the split is at the transformers (which is typically the case)?
