Propose deleting failure for 3.2.5

At least for HTML, the only ways I know of to "create a complete change of main content through an automatic refresh" are to use meta-refresh or script.  Both can be disabled in browsers.  Are there other technologies that have these issues?  If so, we could create a general technique about it.  If not, then I don't think this is a common failure for HTML, and I propose that we delete it.
