Marko A. Rodriguez commented on TINKERPOP-1412:
-----------------------------------------------
Its not about chains of identity() as it is about having an identity() and
wanting it removed so another strategy can concatenate stuff. For instance,
{{FilterRankStrategy}} would like to have {{IdentitySteps}} cleared so it can
optimize {{dedup().identity().has()}}. Thus, if anyone (provders to) ever
create strategies that use {{identity()}} as placeholders, they will want to
have {{IdentityRemovalStrategy}} in their strategy listing.
