Poor draft, the fire will snuff its self out like an ECB. Fire is a bottom feeder it draws air in at the bottom and releases heat out the top: no air= no fire.
You won't be able to snuff out the fire on a short cook and save fuel for the next cook. Charcoal, ashes and drippings all mixed together will draw damp ruining any remaining fuel and also rust out the bottom of the cooker
Once the grease is mixed with the ash good luck pushing that sludge out of a pipe nipple
I agree with all of this. Personally I love simply pulling out my basket/ash pan, giving it a shake over my garbage can to shake out ash and at the same time sift my unused coals, then setting it back in my pit ready to rock. All I can really see the cleanout good for is for washing out the smoker once in a while, and even then I'd want it to be at least a 2" close nipple with no elbows or turns so it doesn't clog.
