It's not always ok to do this. For example, in the main house wiring
panel neutral and ground are connected together, but in subpanels
neutral and ground need to be separate. It's ok to have a couple
volts across the neutral wire if it's under heavy use, but the ground
wire shouldn't have any significant voltage across it. Subpanels need
to keep the two separate so the bulk current of running appliances is
directed entirely through the neutral wire, none through the grounding
If you look at the mainboard, you'll probably see that all the ground
and all the 3.3V are respectively already connected together by a fat
copper trace, which makes it ok. Anyway, it is ok.

Open means they ask that you leave it unconnected.
