It's always harmless to leave it in the expression, the interesting question
is, under what circumstances is it safe to remove it?
For example,
self::node()/abcd
can safely be rewritten
child::abcd
but
self::node()/(.+5)
can't safely be rewritten as (.+5) because you lose the check that the
context item is a node.
