docs: /*
  Old version did not have followLink flag, so to support backwards compatibility
  we check if followLink is a function
  if so, the caller is expecting the old version of this function,
  if followLink is a boolean, caller is expecting new version
  
  *NOTE* all this is only relevant to Listing functions, nothing else uses filters
