The commit also establishes a precedent of leaving off the `virtual` keyword in overrides. Although not strictly necessary, I believe this is good for readability because it makes it clear it is an override and not a pure virtual function, and it helps keep line lengths shorter. We should move towards eliminating the macro altogether, but the definition has been left in with a note on deprecation so that in-progress work will not suffer merge conflicts.
