Re: Focus Stacking
I have to believe creating the composite image "in-camera" would take an enormous amount of time away from shooting. In my 5d4 when I take a 3 shot HDR I can't shoot again for 7 seconds while the camera compiles the finale image. Image processing 20 focus stacked images into 1. Granted, the Digic 10 chip is faster than my Digic 6, but by enough?
Re: GPS
I personally don't need GPS if I drive over to the dog park, or the botanical gardens, etc. But looking back, there have been a few times I wish I had used GPS tracking on a series of images taken over several days. The first example was our trip to Ireland. We did a circle shaped tour of the south side of the country stopping in several cities over 5 days. I wish now I could look back at a map of pins and then see the images taken, location/date/time stamped, along the trip.
Same thing for driving vacations here. Leave Florida, hit a few other states, record and review the trip vie GPS coordinates. Lightroom will do that.
And looking back, in addition to using my Canon body I should have at least snapped 1 photo using my phone with GPS tagging turned on. That could essentially create a map of where we were each day or so.
GPS location tagging can be useful from time to time.
With phone GPS and other GPS, a GPS built into the camera the camera isn't needed as much. I do use the 7D2 GPS also to set the time on the camera so it matches an external GPS.

I didn’t really use the GPS on the 7DII. I couldn’t get it to lock reliably, even under relatively open sky, and it seemed to eat a lot of battery.
I’m actually a fan of the app method. It’s only as good as the phone’s GPS so it won’t work well indoors or around trees or buildings, anyplace the phone has trouble. But it’s always with me.
I use an app called GeoTagr for iOS. It has a companion macOS app that tags the pics after they’ve been transferred to the Mac. It’s an extra step but I like the program.
It does eat a lot of battery, but it usually lasts through a day for me. At airshows or other venues where I take a lot of pictures, I will need to change a battery once.
The GPS seems better in later software revisions. I will turn on the GPS at least once a month because I assume it contains an ephemeris database similar to the other GPS devices I use. GPS takes longer to lock if it needs to rebuild that database which is transmitted from the satellites. The 7D2 isn't as good as a dedicated GPS, but it works most of the time for me. It eventually loses lock when traveling in a commercial jet, possibly because of the limited number of satellites it can receive through the tiny window, or it just has a cheap receiver or antenna. Also, when the cabin crew dims the windows on a Boeing 787, no GPS will work (my personal experience). Outside of that situation, my 7D2 GPS works well now.
I use a BadElf GPS when the 7D2 GPS doesn't work well (airlines). I can be happy with using an external GPS if Canon makes it easy to somehow synchronize the clocks to within a second or two.
I like using a GPS because it documents where I was, and from the location, I can document what I imaged when I get home. When photographing wild life, it documents where I was when I saw wildlife. If I manage to image something unusual for the area, it gives very good documentation for the few people who might have an interest.

I use it for aviation as well as photography.
