With polymorphism, you typically want base classes that provide a general interface, that many classes can derive. In places where you use this pointer-to-base, you don't need/want any knowledge of the derived type. It is an unneeded depedancy, which would only increase compile time, or worse, cause circular dependancies.
I'm not a big fan of RTTI, and not even sure if it would work here. But once you start keeping track of all derived types, you might as well use an std:: variant. It's more cache friendly too, so more performant in many cases.

Works with RTTI?
