The algorithm can be conceived:

Z-depth of new window should be set as "on top" at the point in time
when the user clicks/double-clicks the application icon or starts the
app from the cmd line.

the Z-depth of a newer window, i.e. an app started more recently in
time, should be higher again, even though the window for the
previously started app has not yet started.

We can conceive a window manager wrapper for all "gui" apps:
 - the wrapper passes through all options to the underlying program
 - the wrapper does a single thing in addition: it also "passes"
   somehow (perhaps via an environment variable), the desired Z-order
   for "windows about to be created"
