Oh, I was mostly thinking in consideration to fermenting in a keg where it's useful to have a spare short tube, or a tip when doing a keg to keg transfer. (Along with chilling the keg for a few days to really solidify the yeast.)
I agree, if you're just dispensing, just leave the normal tube as is and pour out the sediment in the first glass. There might be a little bit extra sediment if you let it self carbonate with dextrose instead of force carbing, but it's still not a lot.
