Logitech mice don't use the top surface of the mouse as a multi-touch trackpad, so it doesn't matter to Logitech if the top surface of the mouse is uninterrupted by a charging port or not.

The charging port on Logitech mice is not on top surface. It's on the (slanted) front bottom surface. The top surface is fully devoted to controls.

I think both could be accommodated in a single design.

You mean, like with a notch… It is cool on iOS but not on a mouse… Funny.
