Confusion to whom? Surely the person writing the script would know whether they set it on or not. And I think that if they set it on once, they would do that for all scripts they write in the future and be accustomed to writing with quoted strings.
If you mean it could cause confusion when asking for help, there is that possibility. But I expect anyone who specifically set the quoted string on would normally know enough to mention that in any help request.
If I haven't covered what you meant, please explain.
