member fields of the superclass, I'd expect that a subclass needs to
have a changed SerialVersionUUID if the superclass changes.
Testing this aspect might be in order.

But should the subclass serialVersionUID change just because the
superclass changed? That's what you are proposing. I suspect not,
but again, I'm not an expert in the field.
serialVersionUID = 1L; might be a better choice and might also encourage the developer to update it when he adds things.
