USB-A is not 'just fine'. It's uni-directional. Which is an insane design for something being constantly plugged in and out. It's also low-bandwidth and low-power. Most devices these days have bluetooth, so it isn't really needed except for power and monitors. USB-C is a step-up in everything and I'm happy with only USB-C.
Not everything needs to be constantly plugged. My desktop doesn't even have Bluetooth in it. I'm quite happy with the USB A ports on my PC when it comes to plugging in mice, keyboards, USB storage, etc. If you use USB devices on a regular basis, you'll remember which way USB ports are oriented, and you can just look at the end of the USB cable to see which way it needs to go in.
Having said that, I will say the USB C connector on my phone is far superior, as I plug/unplug it daily.
Power and bandwidth aren't even related to connector type.

You shouldn't need to remember orientation or look at it! You're apologising for a bad design.

Not true! For example the max bandwidth you can currently put through USB-A is 10 Gbps with USB 3.1. Through USB-C it's up to 50 Gbps with Thunderbolt 3.
The asymmetry of the USB-A connector is at worst a minor inconvenience. Definitely not in itself a good reason to break compatibility. And most USB devices are not frequently plugged in and out (indeed, for those that are, Bluetooth is a better choice!)
