Funny enough, with all of the functionality I've lost for one reason or another (read: mods ) I've gotten back...through mods. Because you can't use in-game photomode's rule of thirds graph with IGCS active, I had to grab one for reshade and with it also comes aspect ratios, which means I get back to cinematic and moody compositions.
Couldn't I have done that before in post? Absolutely, but now I can shoot with it in mind and not hack away bits of the shot after the fact.
