Completely understand that it would be nice to change the cursor symbol... I'm not against the idea of having options because as you mention it's all about preferences.
But what I'm trying to understand... what will that gain? Since folks come in here repeatedly asking let's have a "real" mouse symbol. As if the circle is not a mouse symbol.
It will gain the opportunity to change it if you want to. You can ask the same about the ability to change the screen background or the size of the current cursor ball - what do those gain? And it will take away nothing so why object?
