Haven't had much "junk" get in our gearboxes and we leave them open. But I do agree, you can wrap some thin polycarbonate around them.
Most teams have issues with grease getting everywhere. The last two years we switched to a DuPont Dry Grease which has fixed that issue. For a direct drive WCD setup, its a whole lot easier to run open gearboxes too.
Why we do it:
-Lighter
-Less parts
-Internals are Visible
-Easy maintenance (Dog shifters, Chain etc..)
-Easier to teach new kids (not really a design decision just a benefit)
-RC
