Couldn’t it have an optional interest for PDF? To produce optimized PDFs
and accelerate the online rendering (fast web view or something like
that)? If that has any interest at all...

I was thinking about that. Theoretically, yes, to a certain degree, but
PDFs are rarely produced through the intermediate format. The problem:
the feature will only work (have any effect) if the IF is serialized and
rendered/painted later. When rendering is done in one pass, the painter
kicks in before all the resources are known.
