I guess it's just a case of being a defensive shell programmer, but I've always considered curlies-with-double-quotes to be essential with all interpolated strings.
A better way to handle it would be to make curlies mandatory, and then change the definition of variables. Programming style, defensive or otherwise, doesn't really enter into it. If you change the language, do it in such a way that old programs fail, rather than take on a new meaning.
