Nobody fakes depth of field that well, and super resolution (the algorithmic kind, not the real kind) doesn't work that well either. We've been doing research in those areas for 25+ years now, and while some real progress has been made it's not magic.
Phone cameras are doing a lot of heroic stuff to get around the limitations of their optics, and it results in "hey, that's not bad". Nothing wrong with that!
But I don't see why you would want to see that stuff in a digital SLR, say, though - if you take your photography seriously enough to lug that thing around, you're doing post processing on a computer anyway, and you can do all that stuff better there (at least in theory). Now if you were asking why photo processing software on your desktop wasn't absorbing or improving on everything in the phones, that would make more sense to me.
You're right that the best image stabilization is opto-mechanical, but it would be very nice to have access to digital image stabilization as well as in-body and in-lens stabilization. Again, a decent accelerometer can go a long way.
Honestly, most of what I'd like to see has involved image stacking in one form or another. Digital ND filters are the same idea.
And don't get me started on ergonomics and usability. I definitely picked the worst camera brand in terms of user interface (sony), but all the DSLRs and mirrorless cameras I've touched are noticably lacking in that department. I don't necessarily need a giant phone screen like my S9+, but I would expect a device costing $2000+ to at least have a fairly high resolution OLED panel on the back of it with solid touch controls. Meanwhile touch controls are distinctly lacking in any camera I've tried.
Software is important too!

I would like to see a panorama mode also vs firing up stitcher applications. All these should be basic firmware upgrades tbh even on the older models. Features available on a CoolPix entry level camera should not be missing from prosumer DSLRs.
You can fake depth of field, use image stabilization and image stacking to gather more light with a smaller aperture, utilize "super resolution" and/or neural network techniques to get or fake more detail, etc.
I'd love to see some of the awesome work being put into phones carry over into full-frame cameras before the whole pro-sumer market and a bunch of the pro market dissolve.
