Why can't we go back to small phones?

I procured my (second) iPhone SE less than a year ago, although I believe it has been discontinued. I don’t need a larger or more sophisticated phone for any reason at all…not sure what my options will be after this one inevitably craps out - guess I’ll find out eventually!

Dims are 5.45 x 2.65 x 0.29 - the display is 4.7 wide 👌🏻
