I'd prefer an explicit configuration mechanism and an separate
(auto)configuration agent, that speaks to the server and does
things like device probing (with the help of lowlevel device
drivers), etc.

You're talking about things like those special keys (or key
combinations) found on certain keyboard ? Well, they IMHO should
be either handled completely outside the display system and 
*maybe* passed into it by an separate agent. I, personally, 
wouldn't want any GUI application to somehow catch those 
keystrokes, instead configure explicitly who will get them.

Quite simple: map the whole key actions to a larger event codespace.
They could be even represented as text strings in the protocol. (eg.
pressing the capital A could trigger some "KEYPRESS-A" event, an Ä
umlaut would have "KEYPRESS-AE", etc). These lowlevel input events
are then mapped by the compositor to the appropriate applications,
dependent on current focus, etc.
