I'm guessing the reason is that gnome-terminal uses GTK+3.

The release notes for 3.10 have this:

* GDK has been changed to allow only a single screen per display.
  Only the X11 backend had multiple screens before, and multi-screen
  setups (not multi-monitor!) are very rare nowadays. If you really
  need multiple X screens, open them as separate displays.

But, it looks like it was added back in (or at least support for the
clipboard was added) in 3.17.6:
