This is about charging, not how it sends data. And the batteries last a long time for this particular device, so there's minimal downside to unplugging. The downside to staying plugged in is there's a cable dragging around that makes the experience of moving the mouse a little bit worse all the time.
A user has to be thinking about something to make a choice. Depending on the user to think about all these little aspects degrades the experience all by itself.
I guess we have to agree to disagree. To me, it's not about charging at all. It's about wireless vs. wired, and wireless is a buggy, defective user experience. I want to use my mouse full time while plugged in due to poor reliability when unplugged, and only Apple's devices say no--for reasons that don't make sense.
I've never been bothered by a cable sticking out of my mouse.

The reliability would not be affected since it moves data wirelessly. The data will never go over the charging cable so your reasons for keeping it plugged in don't make sense.
If I turn off bluetooth and plug my "wireless" Apple keyboard into USB, it works fine, sending data over USB. There's no reason why they couldn't make the mouse the same way.
