Engines are too strong and reliable.

Totally agree with Jumo. Another issue is that you can run an engine at high or maximum manifold pressure, while at low RPM, with absolutely no consequence, except for a rise in the CHT in air-cooled engines which can still be managed.

However, the simplified engine dynamics is just a legacy of just how old this game is, and I've come to accept it over time. High-fidelity engine simulation was simply outside the game design philosophy at the time, and now more than a decade later we're paying attention to it.

Having said that, there is no reason why pilots should be able to use WEP as a matter of routine.
