As mentioned at the start of the thread, my immediate use case is for
the installer for the VirtualBox Guest Additions, which are delivered as
a virtual CD image which "appears" in a virtual machine when the user
selects "Install Guest Additions", and which is normally auto-mounted by
the guest at a mount point which can't be cleanly predicted. I would
simply like it to look prettier on X11/fd.o-type systems - in the
current iteration the user can click on the icon of a shell script to do
the installation, but it would be nicer to have a more recognisable icon
and the other things that a .desktop file describes very nicely.

Tricky one. On the whole I would say that the initial working directory
and the directory where the application files are located don't need to
be related, but I can't immediately see how a relocatable application
could usefully specify an initial working directory.
My initial googling when I was looking for solutions to this suggested
that other people might also have uses for it. I don't have any links
handy just now, though I could look for some if you like.

Of course, that raises the question as to whether supporting ../ might
be useful for someone. But it would seem reasonable not to support it
until there is a concrete use case.
By the way, I assume you saw
