Yes, I'm advising people to do that, especially after a variable reference as in for ... return $x/item which hardly ever needs a sort into document order so it's better to write $x!item. I had a case reported to me recently where $var was a sequence of three parentless element nodes and $var / item essentially randomized the order because the relative order of nodes in different trees is undefined. Much better to write $var ! item which (a) makes the result predictable, and (b) avoids the cost of an unwanted sort.
