Default Sealing the Lid on a UDS

Fellow Drumheads,
I see a lot of guys sealing the lids to their UDS's to make an airtight seal. I'm not sure why this is important. Why does it matter if the air leaks through small gaps rather than the large holes that you've drilled in the lid? This applies to those of us using Weber lids as well. The gaps are above (although slightly) above the cooking grate and far away from the combustion area. So what's the difference if the exhaust comes out the side or through the exhaust?

The only benefit I see is that the air-tight seal helps distinguish the fire after the cook is through.
