Not quite; mainstream window managers permit you to choose what to do, and maybe default to the (sane) course of notifying, but not actually swapping. Even in the ones that have focus-does-not-follow-mouse as default know better , but it's still an option.

Unfortunately, no. But it is worth noting, of course, that matchbox differs substantially from a standard wm, with it's one-window-at-a-time nature, and that does make focus handling a bit weird. I still think an option (either raise and focus, or do neither and flag the window-list) would work nicely.
