To be more precise, Open in Terminal is not actually built into Nautilus, but it is now part of the gnome-terminal package, which installs the libterminal-nautilus extension (at /usr/lib/nautilus/extensions-3.0/libterminal-nautilus.so). So the version in the nautilus-open-terminal package is now redundant and obsolete.
