Replacing USB-A? Definitely not. There are so many little devices like wireless adapters, hard drives, thumb drives, etc. There hasn't been much of an effort to convert these to USB-C, so they all need dongles.
Replacing micro-usb? Absolutely. It is so much easier to deal with since it's reversible. Especially in the iOS world since it's either lightning or usb-c for devices.
Docking stations? Yes but it's complicated. I connect one little micro-usb cable to connect 2 monitors, a mouse, and keyboard to my laptop. But it's tricky finding one that supports the right resolutions and refresh rates.
