I probably don't know about opacity and filters...

Can you elaborate on what other things are not going to be possible with fragmented content? For example, if somebody wants to create 3d page turning effects (with transforms and shadows applied to pages separately), will it also be problematic for the reasons you are describing?

Also, region formatting allows setting different background on same element in different regions. Is that also problematic if an element has to be rendered as a unit?
