As a European, I'm very happy. USB-A has been with us for over 20 years. It's only disappearing because of USB-C, and USB-C seems to have room to grow. I wouldn't be surprised if it will still be the most popular connector in 2035, and not just because "legislation stops innovation". Making sure there are no weird exceptions to a very good port is reasonable and good.
The idea's nice. I'll still have about 30 unusable micro-USB chargers lying around, though.
Your chargers are USB-A, and you can make them usable with an A-to-C cable.
There are no chargers with micro-USB output port (USB never specified such thing). Micro-USB has been designed to make cables essentially disposable (and not meant to be hardwired into any device), because the more robust side of the connector is in the device's port, and the fragile side is in the cable.
