I think this tag will make people lazy. They should take care of the problem and not just put a band-aid on it. Some content management packages will probably add this by default and a few SEO's will use it but for the most part it won't be used.

The bigger problem is that you are now letting google make a decision. Google will see 2 identical pages and see that they both have the same tag. Your still making google think.

If you are going to go through all this trouble anyhow it is just as easy to put a 301 redirect. Just put in a few lines of code that detects what the right url is and if it is wrong 301 to the right one.

Also this tag does nothing for the pages that are 90-99% identical.
