It's debateable, IMHO. I'd guess it's pretty rare that anyone batting at #8 doesn't at least know which end of the bat to hold, and is often a factor in their selection (see Giles, Ashley).I think an all rounder should probably be someone that is at least a proper #7 bat and at least a proper fifth bowling option.
Might not always be ARs per se, but at least AR adjacent.
