Virtual functions are not space-efficient because they require vtables, and vtables consume memory even if the functions in them are not overridden.
The amount of memory used by a message map, in contrast, is proportional to the number of message entries it contains.
Since it's extremely rare for a developer to implement a window class that includes handlers for all of the different types of messages, message mapping conserves a few hundred bytes of memory just about every time a CWnd is wrapped around an HWnd.
