It seems like it'd be awfully easy to unintentionally disinherit a child
table from a parent.
In a situation where you're only using single inheritance, it hardly
matters of course, but for multiple inheritance it just seems like a
way to shoot yourself in the foot. ISTM it'd be safer to have an
explicit disinherit-from-this-parent operation.

I could live with that. Do we need the parens?
