OK, but for the official OAP artifact, all of these except the power
supply connector (which should remain a screw-type connector) will have to
be changed back to simple 0.1" pin strips. I've found that on the
prototype robot, ribbon-cable runs between simple 0.1" headers for the
signals are simple, cheap and effective. This is what the Magnevation
board uses for all its signals, and the I2C connector on the Mini-ITX
mainboard is a 0.1" pin-strip too, so in the interest of standardization,
I think it makes a lot of sense to use just a single connector type for
all modules.  On a practical level, once you've mastered making up wire
harnesses using ribbon cable, header strips and shrink-wrap tubing, you're
using the same technique for all the signal wire runs throughout the
robot.
