Internally, gnetlist evaluates each and every connection.

I created a small test schematic with some component pins
connected to nc-left.sym and did:

for i in $(gnetlist --list-backends|grep -v "backends\|^$"); do
  gnetlist -g $i -o $i.net 1.sch 
done

For each pin connected in such a way, all backends that worked
without errors output single pin nets. Of course, some refdes
based netlists (e.g. spice-sdb) don't care.

I use the recent version compiled from git, and AFAIK, there is no
gnetlist option to ignore connections to no-connect symbols.

As Gabriel said, this is probably a bug, so you can file a bug
report.

And if you just want to not see nets for some unnecessary pins in
your netlist, just don't connect them anywhere.
