My suggestion is pursue in app feedback and app store reviews with titles calling for an update. I did a Microsoft User Voice entry for the Office 365 admin app not updated to full screen, and Cisco feedback for Meraki.
Apple should start by optimizing the homescreen. No reason they couldn't shrink down the app icons - which are now HUGE - to a smaller size and have more apps per screen. Also wish you could line up icons from the bottom up.
