That's no problem IMO. Two-pass data is always wrong the first run.
In the worst case, it needs an additional run if text moves around
too much. But since it's just another method, which is optional,
this only applies if it's activated and then the user knows what
he/she is doing and that it might be slower.

I think it would be a nice feature. It enables placement of elements
where they logically belong, instead of where they are supposed to
be printed. It's nothing mission critical though, but you can keep
it in mind for a rainy afternoon.
