But many of the changes are only geared towards increased consumption - USB-A / Micro USB can also be operated at USB3 speed.
To design a new connection for something that is also possible via an existing one - is simply stupid.
And also electricity through this - especially!

There are two different micro-USB connectors - one can handle USB3 speeds and power, the other cannot. The one that cannot is the one typically found on phones. The one that can, is often seen on things like external portable hard drives. The two connectors are not interchangeable. Why they are both called Micro-B is pretty silly if you ask me.
USB3, with it's higher speeds AND higher power, requires 9 wires. USB2 only requires 4. The attached picture shows the two different types of micro-B connectors (this picture is too old to include USB-C):
