Undocumented SB32 on latest nRF52832 DK

Hello,

I have noticed that there is a SB32 on the newer nRF52 DK boards (PCB 1.2.1), right next to the debug connector. It looks like this is a reference voltage that is directly applied on the Cortex Debug Connector on Pin 1. If I solder this bridge, will it be possible to flash external modules that are not supplied with voltage? Will this stop the nRF52 DK from detecting the reference voltage on the external board and will it always program the external board instead of accidentially flashing the onboard module?
