Then how does the session manager tells that an application is a WM? How do
you prevent the session manager from starting the WM from the session if
you specify a WM elsewhere?
With the current design, changing the WM is as simple as:
$ myfavoritewm --replace &
And it will be restored along with the session, it's that simple. Anything
else adds non-standard complexity.

Having many users hitting the same bug does not mean the code is fragile,
it means the code needs fixing.
Session management is pretty standard and works well enough, unless we hit
a bug such as this one.
Fixing the bug should be the goal, not reinventing the way of starting the
window manager to hide possible bugs in the future...

It is not a dead window manager, it's the session management not starting
If the WM dies, fix the WM, If the session manager fails to restart the WM,
fix the session manager.
