Simple question for the amp techs regarding backplates

Hey guys, I caught a stream on YT talking to Joe Bonamassa going over his live rig. I noticed he had all the back panels off his amps, with fans blowing across the tubes. It was in a rack, so completely protected, but it got me thinking. Most of my amps will live a lonely life alone in my man cave until my kids get them. I have one rig I use if I want to go anywhere outside the cave. Is there any benefit to keeping the back panel on, other than tube protection? It seems like it could extend tube life, but I wonder if they also provide any significant shielding at all? I've seen weird stuff affect shielding, so figured I'd ask here. I didn't find anything on google, just guitar back panel plates. I also doubt bare wood would do much, which most are, but I have some that are steel or partially steel.
 
No shielding benefits to a piece of wood and tolex. Leave 'em on, take 'em off. Doesn't matter if your amp sits at home all the time.
 
oh geeze, I hope you're pulling my leg! I'm not gonna be shocked either way though, lol. :ROFLMAO:
I'm afraid I'm burnt out on the topic but others may be kind enough to explain. It all boils down to this:

I take them off when i get an amp. I severely dislike the added step when changing tubes. At times I just kept the chassis out so that i could have full access.
