That's an excellent reason for making single-process available, but not
an argument (either way) for making it the default.  It certainly doesn't
sound like a problem experienced by, say, evince.

What is the GtkApplication solution to dealing with different environment
variables, including DISPLAY and LANG?

I believe the single/multiple instances is a decision for the developer and
not one Gnome or Gtk should have an opinion on.
