I asked this question years ago to an old retired Chrysler mechanic and he said the design was intentional in case the oil pump locked up it would twist the end ot the distributor shaft and cause the engine to stop running and essentially protect itself from further damage running with no oil pressure. Looking at it in that light, I would want "just enough" distributor tang in the slot to drive the distributor. .090"-.150" seems sufficient. "It doesn't take much" to turn it at all.
