I wasn't talking about a config file change fvwm2 -> fvwm3.
Consider this layout:
+----------+ +------+ +-------------+
| | | | | |
| "1" | | 0 | | |
| | | | | "2" |
| | +------+ | |
+----------+ | |
+-------------+
The user has a built in screen (0) and an external screen at home
to the left of the builtin screen ("1") and another external screen
at work that is to the right of the builtin screen.
The user must (I say "must" because we're not talking about a
random low quality wm but about "fvwm3") *must* be able to write
one config file that works
* If only screen 0 is present (0 is the primary screen).
* If screen 0 and "1" are present (primary = "1")
* If screen 0 and "2" are present (primary = "2")
without changing the configuration file in between. More things
that shouldn't require changing the config file:
* Rearranging the monitors (i.e. "1" is to the right next time)
* Replacing an external monitor with another one (e.g. bought a
bigger monitor)
* Adding a second external monitor, e.g. using "1" and "2" at
the same time. (Of course this may require selecting a new
primary monitor, but that would be only one config line).
Well, maybe the user has to do the mapping manually, but hopefully
just once.

Yes, but other window managers probably don't allow the user to
specify geometry strings that address a specific monitor. If you
cannot do anything with these monitors but move windows to the
other monitor manually, then of course there isn't much you can
change in the config file.
