When somebody hands you files on a flash drive you need an adapter, where I just plug it in and go. When you take an SD card from a camera, or want to flash an RPi OS on it or whatever, you need an adapter. I just plug it in and go. When connecting a monitor, you need an adapter. I just use a standard HDMI cable and go. USB-C users are the ones that need a bunch of cables and adapters. This may change if the Apple fantasy of every device in production switching to USB-C ever comes true.
Having USB-A ports would make no difference here, I want to deal with LESS cables, not DIFFERENT ones.
