The ship has sailed on USB type A.
Agreed... let's get over it. No need for dongles either for many peripherals since you can buy cheap – cheaper than many USB-C to USB-A adapters – USB-C to USB-A/B cables from, say, monoprice to replace existing USB-A/B cables. As for USB memory sticks, there are very affordable high capacity sticks now with both USB-C and USB-A plugs on them for flexibility. I have one USB-C to USB-A adapter for USB emergency purposes
