I had the *dontzap.py which I presumed stole the ability to restart X
but had to install the package to run the command from terminal.

emacs call for a lot of ctrl-alt commands but i doubt anyone using that
would mistake that keystroke.

I would like to see the old default behaviour returned for update
notification as well. though I suppose waiting a week for notification
might save some from broken updates. Just another thing to change
every fresh install.
