Explain your idea

This is a relatively simple suggestion, that fluid pumps should be able to have their redstone behavior inverted with a screwdriver like other IE machines.
My specific usecase that has brought this up is trying to set up a redstone trigger for fuel pumps based on comparator/probe outputs from tanks: if a tank runs empty, probe sends a redstone signal to activate a pump for a secondary fuel. However, granting that I am not a redstone wiring expert, I don't know that it's possible to actually do this with redstone wires as probes default to a lowest possible threshhold of 1, and thus only send the inverse signal of what I need, requiring the addition of a vanilla redstone torch to invert that signal (and breaking the whole visual style of the setup, pictures attached of my specific setup with red pipe being HC diesel, yellow as diesel, and brown as creosote).
It's understandable that the feature is currently not implemented due to the potential for abuse in lag machines or the like, however given how integral pumps are in fluid handling and how well integrated redstone wiring is I'd argue the utility for setups such as mine outweigh the occasional server troll (though of course that final opinion is entirely yours to make).

To do an inversion, you can use the Redstone Switchboard, or you could use a Machine interface to measure the tank in a more advanced way.
