Not quite.

What i am pointing out are neither complex nor any magic under-the-hood. They are simply techniques in the C++ repertoire well-known since the early 90's and used in all high-performance C++ libraries.

tialaramex made a big deal out of overheads in C++ dynamic dispatch (which incidentally are pretty minimal) using a trivial example, when performance focused (both time and size) C++ programmers do not use it that way at all. Modeling in C++ can be done in any number of ways and is driven by specific perspectives of the end goal.
