colibri notifications

[Roman Shtylman]

I dunno if a decision was reached on this at UDS, but I am gonna drag
this back up. I don't think we can wait on upstream here as their
views seem to diverge from ours in this area.

The basic question is, do we, or do we not, enable colibri
notifications by default? Do we have user feedback about this? Should
we do more to make it clear you can enable colibri style
notifications?
