That mesh should operate like a heatsink for the bridge. If you remove it...I guess...the bridge would get hotter--faster............maybe it will burn out quicker or not.
I haven't heard of the bridge melting from such extra heat, or anything like that. Basically, I think any internal wires get their solder melted off and the wire disconnects on its own--I think.
I agree, good point. We'll see how long it lasts.
