I guess I would not, as I would want the option to use the input via diffusion stone, then switch to input via regular port; again, to be able to have CO2 come into the keg as it was emptied without being input from the bottom in a very agitatiousexpyisticfragicalirupus method.I had to look up "carbing lid" to see what all the fuss was about. The one I saw pictured only had a gas inlet and a PRV. No liquid port at all. Seems one could create the same function on standard lids by replacing the gas tube with some PVC tubing and an aeration stone. No?
