Comment 5 for bug 366644

The policy would suggest that GNOME Terminal is not suitable either, since its -x is xterm's -e, and it doesn't support -T.
We follow GNOME Terminal behaviour in this regard, our -x is xterm's -e and we do not support -T.

I suppose that means that on the face of it, we should not install the x-terminal-emulator alternative.
Instead I wonder if the Debian policy should be updated, since x-terminal-emulator will presumably point to GNOME Terminal on the vast majority of installs.
