The only reason that I was able to discern for removing that metal protrusion on the lower left side of the block (to the right of the old dip stick hole) was that it gets in the way of the beautifully fabricated RSport engine stands.
That alone, however, was reason enough to hacksaw the thing off.
The engine stands are $175 for the pair. From RSport in Pennsylvania.
