It already does this, however the timeout is longer than 10 seconds. It will power down automatically after 2.5 minutes.
I also agree about it powering the servos - it would be a nice enhancement if the servos could be powered off the regular battery (and perhaps fall back to the backup if the main battery dies). My reasoning is that by it being the only source of power for the servos, it's not really a
backup battery anymore, but just another required power source. When I think of a backup system, if the backup fails while the primary system is functional, the user shouldn't notice. In this case, if the backup battery fails (and assuming you use servos on your robot), your robot will be crippled even if the primary battery is fine.

Unfortunately, yes...
Under the "RESET Button" section of the RC reference guide:

If the Robot Controller is running from Battery Backup power, you must press the RESET button to power off the RC after Main power is removed.

I remember someone on our team figured that out the first day we had the kit, but it wasn't me. I guess my engineering instinct kicked in: why read the section on the "reset button"? Everyone knows what a reset button does, right? D'oh.
