// A lot of clients bind keyboard and pointer unconditionally once on launch..
// Initial clients might race the compositor on adding periheral and
// end up in a state, where they are not able to receive input.
// Additionally a lot of clients don't handle keyboards/pointer objects being
// removed very well either and we don't want to crash applications, because the
// user is replugging their keyboard or mouse.
//
// So instead of doing the right thing (and initialize these capabilities as matching
// devices appear), we have to surrender to reality and just always expose a keyboard and pointer.
