Why did the RS-25 go dual shaft / dual preburner design? It seems like having your fuel-rich preburner next to a LOX pump caused a heck of a head ache in making a crazy seal... so why didn't they go with a common shaft like most other engines? @DJSnM @torybruno @elonmusk @lrocket

Common shaft only works if optimal rpm is similar for fuel & oxidizer
