I'm not opposed to doing it, but I feel that it's not sufficient because
it doesn't say why that abstract class exists (i.e. what it is that
makes it meaningful to group those different classes under that abstract
class).

To me it's akin to describing a particular image by listing the pixels
it contains and their color but without saying what the
image represents.  We may be able to use our brain to figure out what
the image represents, but it's not always obvious that everyone will end
up with the same understanding.

How 'bout the patch below?
