---------------------------------------------------------------
[~julianhyde] I know RelFieldTrimmer, but it only used before the volcano phase
as I first mentioned. Is there any change we can do it again after the volcano
phase?
?? Current we only trim filed before node went into volcano planner. Should do
it again when finished volcano phase.??
