I think you cheered too early. While it is true that comm-central's XBL 
bindings have all been removed, comm-central code is still relying on 
XBL bindings from mozilla-central, most prominently, the textbox. So 
de-XBL effort is *not* finished yet.

We can also expect bustages when M-C migrates their last remaining 
bindings to custom elements.
