weston output when multiple shells load

When [core]/modules is not defined in "weston.ini" or when it's explicitly set
to desktop-shell.so, trying to load tablet-shell.so via the "--modules" command
line argument does not work as expected (and vice-versa).  In this situation,
both desktop-shell.so and tablet-shell.so get loaded.  The only way to
"exclusively" load tablet-shell.so is to specify it in weston.ini (see
attachment) under [core] via "modules=tablet-shell.so" option.

Loading a Weston "shell" from the command line is, thus, ambiguous.  It is
unclear which wayland shell interface is active in Weston when two shells are
loaded.  Does it make sense to allow multiple shell interface implementations
to coexist at Weston runtime?
