While it's a clearly established fact I'm obsessed with low-power operation (I think I need help), one of the biggest constructive-criticisms I have of the MicroMod Carrier Boards is that they all have a 10 kΩ/20 kΩ voltage divider that cannot be disabled without cutting a PCB trace or desoldering a 0603 SMD resistor.
Even for your average user, a constant 0.2 mA draw at 6 V can be non-trivial.
For future versions of MicroMod carrier boards, I'd highly recommend putting a jumper (or FET) between VCC that would allow users to easily disable the voltage divider.
While I would suggest using higher value resistors with a decoupling capacitor to decrease the quiescent draw, I suspect the whole point of the low resistance is to be compatible with a wide range of processors, some of which handle high impedance worse than others (e.g. the Artemis really struggles with this).
