Just curious: wouldn’t it theoretically be possible to delay opening the output file until the first \stattext? Or is there already stuff going out before that, such as preliminaries that go into the PDF?

I think being able to name the output file in the preliminaries in the TeX file would come in handy and prevent more complex workarounds with scripts. But it is not essential as workarounds are possible.
