Using exclusively IBus in GNOME compositor is ok. But I do not think 
IBus could replace a Wayland text protocol. For example the GNOME screen 
keyboard (caribou) does not use IBus but some GTK+ module hack (so it is 
broken with most non GNOME applications even when they use IBus).

That is not true GNOME shell can support the Wayland text protocol and 
still use IBus and a gnome-shell keyboard exclusively without the need 
to make anything replaceable.

There are currently some issues with the text protocol (which we noticed 
in real world embedded projects), I will propose a fixed text protocol 
soon which will fix this issues and should make it fit to become a core 
Wayland protocol.

Note this is all about the text protocol which should be used between 
applications and compositor I do not really care about a protocol 
between compositor and virtual keyboard (input-method protocol in weston).
