Backyard Kingman w/welded in HMP

What would the reasoning be for "welding in or not" the HMP on a Kingman ? Is there a perceived advantage one way or another. Just asking as I want as much information to make an informed decision when purchasing at some point. I guess it doesn't even have to be about this model in particular but better if it is.
Would there ever be a reason to remove the HMP. Does it seal better when welded in thus more temp control? Could you ever see a reason to take out HPM and use the smoker without it ?.......well I guess there would if you're gonna use it as a BIG grill. I guess I'm thinking out loud now.
Your responses would be greatly appreciated. Thanks in advance.
