But still can't tap to pull focus. Ugh.
What for? I don't do cinema with such a tiny body, and don't expect anyone to do so, either. Flexible spot with AF-C is more than good enough in my experience, especially with the large focus box. Focus pulls with the front ring are also doable, especially when it's just for effect (i.e. to emphasize a product or location, and not a transition between two characters in dialogue).
And vast majority of people will never notice the difference in IQ unless comparing frame grabs, or viewing full screen on 4k. If mostly uploading to YouTube or Facebook or social sharing, difference will never be noticed.
Oh, how wrong you are! I can tell them apart on a 720p monitor in a blind test (yes, really). My wife can, too, and I'm guessing anyone with healthy eyes can. The superior color sampling and effective resolution of a UHD file is evident, even when downsampled. There's no contest, really.
Really depends what the video is needed for.
Yeah, sure, but 4K is an advantage for everything if the processing power is there (and it's becoming more common). Crop, rotation, noise reduction, stabilization, exposure and color adjustments - it's just so much more flexible.
