This allows users to quit the application using Ctrl-q. Also see: #23.
As you pointed out correctly, the HIG doesn't enforce this shortcut, or at least not in case an application doesn't implement (other) shortcuts. However, I would still say that this way, the app feels more like a Gnome app, and fits better with the standard Gnome workflow. So, there's a pretty okay reason to implement this 🙂
Moreover, Luminance is an app that you don't need or want to stay in for a long time. This change facilitates that use case by allowing users to apply their muscle memory.
I understand not wanting to grow the codebase, but the change is fairly small.
