The new wording would be:
Questions concerning problems with code you've written must describe the specific problem and include valid code in the question to reproduce it. See SSCCE.org for guidance."
This is intended to target those questions that use one of the many alternatives to jsFiddle that are now available. The intent is to codify the requirement to put the code in the question itself, and not in an external page, in the actual close reason.
Rather than change the close reason unilaterally, we're asking for input from the community.
