Could you explain why you are of this opinion? Is it a concern about complexity of implementation?

Adding a new method to a base class shouldn't risk breaking existing subclasses.

If folks want to retain the base class implementation, they can request that explicitly (and doing so isn't redundant at the point of subclass definition the way it is for methods defined in the class body).
