W/T as it's once was called. Is stupid, idiotic and died a year ago when I started work on Cura (still called SkeinPyPy back then). It was the initial trigger which started Cura.
Basicly it comes from "oh, we cannot control the amount of plastic coming out of our nozzle, but it is steady flowing over time", and if you have a steady flow over time, keep the nozzle speed constant, then you have a width of lines depending on the height of your layers.
Also, people that originally made the Skeinforge software loved ratios. I think they had a ratio fetish. But normal people are no fan of ratios, they are difficult and require you to do math in your head most of the time.
But the W/T doesn't make ANY sense once you have control over your extrusion, which we have, because we have a stepper motor on our filament. And with that stepper motor comes control. And with that control we can do something called "volumatric extrusion", instead of randomly guessing and tweaking the extrusion, we can perfectly control and measure the extrusion. We know how much plastic goes in, and thus how much goes out.
Cura does all the nasty math for you (As computer are good at math. Humans are not). The machine knows how much it needs to turn the stepper motor to push 1mm of filament to the nozzle. Cura knows how thick your filament is (because you tell it Cura), and the rest is just math. Which, once again, we are to lazy to do and will be left to the computer.
So, anyone who still uses W/T right now has a very old machine without a stepper extruder. Or a ratio fetish. (or both, most likely)
Cura 5.7 is here and it brings a handy new workflow improvement when using Thingiverse and Cura together, as well as additional capabilities for Method series printers, and a powerful way of sharing print settings using new printer-agnostic project files! Read on to find out about all of these improvements and more.
S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
(Sorry, was out of office when this released)
This update is for...
All UltiMaker S series
New features
Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

NO. Nor you want to mess with it.
