In search of a way to create another shortcut for restarting X server.
Mainly because I accidentally find myself doing CTRL + ALT + BACKSPACE a lot.

There are two steps to requesting a feature like this.
Has somebody already requested it?
Take a look for similar 'Wishlist' bugs in the upstream bug tracker as well as Ubuntu's bug tracker at (launchpad.net). If there is already a bug, read it. If the bug is still open, subscribe to it.
If you are the first, then file the Wishlist bug
Um...be aware that most upstream developers are often volunteers - they work features that interest them, and they tend to refuse (or ignore) requests for features that do not interest them.
Rather like agreeing to help paint your neighbor's fence - you might agree to do it out of altruism...and you might get bored and drift away from the project after a few minutes.
Of course, if you are skilled and wish to code the feature yourself, that's a different story!
This should do it 18.04. On terminal:
gsettings set org.gnome.desktop.input-sources xkb-options "['terminate:ctrl_alt_bksp']"
