What you prefer here depends on what languages you are used to
do (e.g. C++, Java), how much you use OOP for anything, your
use of unittesting and mock objects, your need for speed etc.
I actually use that quite a lot. Additionally compiler technology
exists now to finalize methods that aren't overriden. It is also
possible to generate code that replace the virtual dispatch by an
simple if if only 2 overrides exists, or even provide a fast path
for the most common override, only conditionally doing the
virtual dispatch.
In other terms, as long as the compiler know about all the
overrides, it can do better than the programmer manually
annotating final/virtual.
