Is there still a way to do a pre-hook on what used to be OnTooltipSetItem?

I want to operate on the tooltip of items before any other addons added their lines to it.
Before 10.0.2 I executed this code (a few seconds after login, to make sure that all other addons have already registered):

local OtherScripts = GameTooltip:GetScript("OnTooltipSetItem")
local function RunOtherScripts(self, ...)
  if OtherScripts then
    return OtherScripts(self, ...)
  else
    return
  end
end
 
GameTooltip:SetScript("OnTooltipSetItem", function(self, ...)
 
  -- Do my stuff with the untouched tooltip.
 
  -- Then let the other addons append their lines.
  return RunOtherScripts(self, ...)
end)

How could the same effect be achieved with the new TooltipDataProcessor?
