They do have software to pair to your phone. I am most familiar with Fuji’s solution for that, which is, to put it charitably, execrable. It is painfully slow and glitchy. (I’ve heard better things about Nikon’s latest, but I haven’t used it.)
Thing is: I think that would require a partnership with Apple or Google, or perhaps Samsung. I think you’d need a lower-level API for very quick pairing and a smart handoff to a low-power mode that doesn’t suck your camera battery dry over the course of about 4 hours.
Cellular networks don't seem fast/cheap enough to upload thirty 100MP images from anywhere you happen to be (or 4K video). 5G is not going to be there all the time when you are out in the woods. Pro photographers often carry a hard drive that you can plug an SD card into to backup your photos immediately in the field. When they get home they plug the drive into a computer and run ingest software (there are a variety of these available) and automatically all their photos are then in a known place ready to be reviewed, edited, etc. It's not wireless, and it takes a little discipline and takes some time to research and set up, but once you have a system it would seem to be fairly painless (haven't tried it yet myself) and would make your photos and video available quickly without having to think about it much.

I don't know how it holds up against newer DSLRs sensor-wise, but frankly I think those have long since surpassed my needs anyway. I might try to get my hands on one just to play with the software experience.
The quality of video is massively better, however. Just no comparison.
My ideal would be for Apple to buy Blackmagic. Probably wouldn't, but... can you imagine if they did?
All I want, like I think you're alluding to here, is a micro 4/3rds interchangeable lens camera that has good integration with my phone. Apple would absolutely kill it if they had one with their camera ISP (even with an older CPU*), and just instantly dumped the photos into your library on the phone.
* except for a few action/waterproof ones
* say the A12, it's being used in the new AppleTV, so why not.
It would be much more interesting to me than the Beats acquisition.
My favorite methods was to remove the SD card from the device and plug it into my computer thought a clunky adaptor. Usually I would do that once a month.
Is that not a option anymore?
The cable is in my camera bag, and it takes less than a minute to do the import.

It's not the end of the world, but it's enough friction that I tend to handle review/editing in batch rather than after every shoot. That's a luxury that I have as a hobbyist, since nobody is expecting me to send them my edits right away.
UX is all about small changes that have a big impact to how you use something. And the physical inconvenience of digging through my adapter/dongle nest is a deterrent, as is the clunkiness of Adobe Lightroom.
What I really want is an iPhone software experience paired with the physical ergonomics of a specialized device like a DSLR/mirrorless camera. Whoever can deliver that will get a lot of money from me. I want real connectivity built into the device made an integral part of the experience, not what you have today which is usually some half-baked thing where you have to attempt numerous times to pair over bluetooth with the unpolished companion iPhone app.
