Interesting comment ...

"The CENTER element is exactly equivalent to specifying the DIV element with the align attribute set to "center"." except it is clear by looking at the tag that it is centered. If this was a valid reason, we could depricate <strong>, <b>, all <h> and other tags and say they do the same thing as <span> with some css. besides, XHTML doesn't even recognize HTML5 tags such as canvas. It is only deprecated because of the war against marquees, centers, tables, frame which is purely religious, as they all have a place. – Dmitry Jun 5 at 18:23
