Well Technology has pretty much advance. Traction Control is more towards performance than for safty. The word usage is the thing of what its marketed for.
1.The Driver is the most important. Putting that aside. How you drive a FWD is different with
RWD ether way.
2. The laws of phyics. Weight on the RWD really does make a differences with snow tires or good traction.
MR layout.........sort of good with the right tires and weight locations for the front wheels.
3. Tires is what is touching the surface. yeah I think you know already.
4. The more advance of todays cars. have this future. with is ESC.
I think your looking for the usage of Electronic stability control (ESC). But its pretty close/same with Traction control. But ESC more works with the ABS, Wheel sensor,etc.
But its only works well with the right tires such as the stock tires or Snow tires. The better equipment. the better the computer system can help you with good feedback.

From Wikipedia
ESC incorporates yaw rate control into the anti-lock braking system (ABS). Yaw is rotation around the vertical axis; i.e. spinning left or right. Anti-lock brakes enable ESC to brake individual wheels. Many ESC systems also incorporate a traction control system (TCS or ASR), which senses drive-wheel slip under acceleration and individually brakes the slipping wheel or wheels and/or reduces excess engine power until control is regained. However, ESC achieves a different purpose than ABS or Traction Control.[4]

I know ESC have different names with different auto car makers. But they are more common in high end cars than most standard cars.
