Hey could we revisit this topic and see what still is blocking ibus
1.5 from Ubuntu?

The 'separate input sources per window' feature has apparently
returned which was a big blocker last year.[1]

I believe the other big blocker was creating an indicator for
ibus-1.5. I don't think anything has been done on that yet since the
Desktop Team doesn't really use ibus themselves which makes it harder
to ensure that it's working correctly. I believe we need some kind of
indicator-keyboard anyway to avoid needing to keep the keyboard plugin
in gnome-settings-daemon at 3.6 indefinitely. There's a basic mockup
on the wiki[2].

Was there anything else serious enough to still block ibus 1.5?
