Limiting transparency to only the "normal" version stems from the
days when that was the only transparency mode supported by Flash-
unfortunately the base assumption that this is the only transparency
mode is pretty ingrained into swftools code base.
(In particular, the gfxdevice_t interface doesn't have the concept
of filter operations on grouped elements)

The "-s breakonwarning" switch will help a little bit, as it'll
terminate a pdf2swf process if it encounters something it can't handle,
thus allowing you to fall back to different parameters.
So you can do something like:
pdf2swf --flatten -s breakonwarning file.pdf || \
pdf2swf -s poly2bitmap || \
pdf2swf -s bitmap
