default <T> AttributesSetters removeAndThen(AttributeKey<T> key) {
        remove(key);
        return this;
    }
Removes the value associated with the specified {@link AttributeKey} in the
{@link AttributesGetters#ownAttrs()}. Unlike {@link #remove(AttributeKey)} this method returns itself
so that the caller can chain the invocations.

<p>Note that this method won't remove the value in {@link Attributes#parent()}.
