I used to shoot wedding video as a side-gig, and I had a range of cameras from the T2i to the 6D. I also owned a few P&S just for fun. Since the 7 Plus I have sold all my P&S cameras. The only advantage they have now is the longer reach, but I rarely actually need a zoom lens for a random shot. If I am doing anything serious I bring a DSLR.
The main problem is I always have my phone on me, and carrying around something like an RX100 is a pain because of how thick the body is. It is not really pocketable, meaning it goes into a larger bag. Then if I have a larger bag, I might as well bring a better camera.
I have the opposite feeling, the RX100 is small enough that I can just stick it in my suitcase/bag and go. If I bring my 5D with I feel obligated to get all the lenses/flash and associated crap and then I'm stuck with a huge 10kg backpack.
