I used iPhone 4 briefly before, until I get iPhone 6 Plus, then 6s plus, then current iPhone XS Max. I used to love big phones because of larger screen and naturally can see more contents. Now I think I can see people preferring using smaller iPhone and buy iPad for some media consumption.I just don't want to use my 8 Plus a 3rd straight year regardless of the nice, wide aspect ratio.
To the rest of your post, all I can hope is Apple addressing this issue in next generation iPhone or two. PWM sucks.
