It's neither radical nor insane, but what if you want to create PDF 1.3, 
and don't have any transparency? The basic capability is there. I think 
the default setting for Scribus export is 1.4; the warnings from 
Preflight Viewer are nonetheless a good thing -- we might change the 
language to "advisory", but I think it's still worthwhile.
