imagetoolbar meta tag and IE versions

Question

There are quite a few questions here on SO about the following meta tag not being HTML5 compliant and therefore will not validate when using :<

Answer 1

Apparently, the Image Toolbar was only a feature in IE6. It was replaced with the contextual menu (right-click) in subsequent versions.

IE6 is dead so I won't be concerned about not using this meta tag any longer.
