I disagree with putting hairpins in the middle. Maybe as an option, but certainly not by default. It could really mess up the layout if you have cross staff beaming or ledger lines used in between the two staves.
I stand corrected. It does not. You can force notes from staff to display on the other, but the beams don't connect. You can indicate slides/gliss across staves, however (that's what I was thinking of when I said cross staff beaming... brain fart on my end).
