USB-A also became so widespread that they became wall plugs in their own right, so at least those will stick around a lot longer unless people start hiring electricians to change their plugs.
I have charging cables (with USB-A on the power side) in multiple places around the house, using the 5V/1A adapters that shipped with iPhones over the years. This works fine, though it is slower than the "fast charging" we've grown to expect these days.
The device end of these cables are miniUSB (bicycle lights), microUSB (external battery pack), USB-C (my partner's noise cancelling headphones), and many of them are Lightning (Airpods, Airpods Max, iPhones, iPads, Apple TV Remote).
There's a few exceptions. If the USB-A jack is rotated sideways on the device, then "up" could be left or right. And if it's a cheap off-brand sweat shop connector, then the logo may be on the opposite side. A sign that it could break quickly too.
