Hmmm on second thought, maybe we could do IHandle<TSelf> : IEquatable<TSelf>, IEqualityOperators<TSelf, TSelf, bool>? At this point we totally negate the need for IsNull as users generalising over T: IHandle<T>>? Could maybe keep this non-generic interface and DIM it in the generic one if we want (is that a thing?) If we go that route no changes will be required to TransformHandles other than the base list.

public bool IsNull { get; }

Could we do this == default to make it agnostic to non-pointer-sized handles?
