Last time I did an install, a debconf question was actually asking about
the locale.

Then it's unrelated to Xfce, and you want to include that in the base
system. I would still disagree, but that wouldn't be my call anyway.

I'm sure you can find a lot of slightly convoluted scenarios. I'm sure
we can find a lot of them for a lot of packages, actually.

Again, I'd disagree with that, but still.

That's not just a question of installed size. A lot of people want to
keep a somehow minimal system in term of disk, memory, CPU time, and
which doesn't get in their way. And some actually chose Xfce *for* that.

Even though it's quite hard to achieve these days, Xfce is designed to
be modular, and will (apparently) happily support gnome-orca if
installed. Fine.

In any case, the original bug was about adding dependency to
xfce4-session, and the answer is no (and the same applies to the xfce
task). If you want to add gnome-orca to the base system, I don't think
it's the right place.
