I think in the future I will do some rewiring on the batteries and charging system and would like to remove this. Can anyone cite a reason such as ABYC recommendations for keeping this original kill switch or is it just overkill?

There are 3 twist switches in the port quarter cabin of the First 42. One each for each of the original batteries and a third that controlled power from either or both of the batteries to the engine starting circuit. I am not sure why one would have also installed an Off-1-2-Both switch as it offers no advantage over the original switches. Nor do I see any reason to disconnect or replace them as they--by your description-control power to the 1-2-Both switch and are/would be a positive disconnect.
