It depends on the application, but it often is a question of size.
If you need to optimize the size of a class (usually because you need
to make millions of instantiations, and you need for them to be as fast
as possible and take as little memory as possible), even one additional
pointer may significantly increase memory usage.

I'd say the size issue is (at least in my experience) significantly
more prevalent than the non-POD issue.
