I find it funny that you are complaining how WRC is not the "best and latest tech" without limits when by own admission it hasn't been the case for the last 33 years!! (in rallying) For Formula 1 it's at least 26 years or more as well. (if you count active aero and turbo engines it's longer)

Even with the limits it's quite certain that the 2022 cars will be faster than 2011-2016 cars and likely not much slower than 2017-2021.
