People use notes for all sorts of things. Sometimes it's just "X has changed", recording details for when they can get back to a PC and can map it properly. Sometimes it is recording the state of something in a state of flux. In neither case does closing the note remotely help.
Full disclosure - I'm from the DWG and we get complaints about people opening lots of notes without survey _and_ closing them (although probably more about the latter).
If you have visited an area and find that a note (especially an old one) is no longer relevant then of course it makes sense to close it, but I suspect that this may not be the case here.
