But how would it look if every app did system wide notifications for
everything. You would be unable to tell easily where things came from,
and you would be constantly interrupted with stuff, which is contrary
with the shell design goal of gettting out of the way.

Also, just because e.g. delete is an async operation doesn't mean you
have to wait until it is done to show the undo notification and hiding
the contact. I did a hack like this with the notes "dot" where it runs
the modification operation in the background, but immediately changes
the UI for it.
