A self-contained package should not install stuff outside its prefix. So,
if the user says it should install under /opt/appname, there should be
nothing in /usr. That's what I would expect, at least.
Now, if you want to have the menu entry show always, you should add it
to /usr/share/applications. If XDG_DATA_DIRS does not point to /usr at
all, it's because the user chose that way.
You'll probably need to make your application be instead a script that
sets PATH and LD_LIBRARY_PATH and other variables, as necessary.
But note that, as I said, it may be difficult to interoperate in the
future if you run an app that expects the system to find stuff that is
outside XDG_DATA_DIRS (e.g., systray app telling the systray to show icon
