I’ll also throw this point into the mix as well…
As I am trying to create a percussion/music book of my own, I’d like it to be in an e-format. I have messed around with iBooks Author (Mac - iBooks stuff), and it is very cool so far. But, if I plan to use the iBooks format where the book will be consistent from iPhone to iPad to Mac, I have to use their templates. If I use the “e-pub” format, when you switch from device to device, there is no guarantee that it will look the same. That is where graphics export would a huge benefit. I agree that when Dorico is better equipped at handling text it will be very easy to create to book, etc. However, going to different formats will still require the exporting of graphics.
