Although it may be possible to emulate using additional markup, what I would really like to see is an implementation of column-break-before, -after and -inside. Couldn't be happier with Prince, but the one thing I miss from working with fo is the use of 'keep-together' to avoid typographic "orphans" in multicolumn layouts.
I'm amazed by your product,
