no, the plan is essentially to have the server hand the driver fully
initialized device structs during PreInit so that the driver really only
calls the options parser and inits whatever it needs internally.

based on that, we should be able to get the hotplugging information into the
device struct, thus making in-driver hotplugging code easier.

the goal is to have evdev split mixed devices into a X11 keyboard + mouse
device without having the hotplugging hacks that we currently require in the
wacom driver.

what changes did you have planned?
