It looks like there's a method available to trash items on macOS 10.8
and above, so I suppose that's the logical thing to use.

macOS < 10.8 uses some Carbon API, which I'd rather not bother with,
and GNUstep doesn't support it at all, so I imagine it's as well using
the XDG location or whatever the default is.
