Hi Hans, using that produces a pdf which fails compliance with PDF/X-1a as
the BleedBox is not set. But notice that if it did work, the sizes of
TrimBox and BleedBox would be based off printpaperwidth and
printpaperheight. I need them to be based off paperwidth and paperheight
(for my documents all have printpaperwidth – paperwidth ≠ printpaperheight
– paperheight).

(Apologies, I initially replied to just you and not the list as well.)
