Yeah, I wouldn't expect this value to be too large in practical applications,
although for some reason we do currently support very large values here.
But with a PointerInt pair this would become too limited. And we don't need to
hold both at the same time, it would be redundant as otherwise having a pointer
to the declaration would provide the template depth.
This would be more like using a PointerUnion with a pair of pointers, where you
are storing an arbitrary integer instead in one of those.
