I used to carry my XT-2 and a few lenses in a small bag for trips. It's a terrific camera and system. However, I just carry my iPhone now. It has three physical focal lengths and two others emulated that look a lot better than just crop and zoom in Photoshop.
There are definitely situations where a larger camera would definitely excel, such as >200mm focal length shots and highly creative bokeh. But that night shot in the plaza, for example, would look great on the latest iPhone. Even if I wanted to print something in a larger format, the new machine learning image size upscaling in Pixelmator Pro (Mac) or Photoshop can produce very nice results.
I'm not selling my Fujifilm GFX 50R or XT cameras and lenses, but they are not in use as regularly as they used to be.
