The dependency was removed in the 4.14 update and nothing depends on x11/xfce4/orage these days.
I wouldn't miss it in neither the main meta/xfce nor the -extras meta package: the tray plugin provides a drop-down calendar version on click which looks just like the standalone GUI provided by orage. Then again, if it isn't installed by any of the meta packages, I wonder how discoverable it is... orage already skipped a few releases, so maybe it just isn't that important/used these days?
