Actually, it does break the web, if we talk about web of the future as well as
web of the past.

This attribute change makes an assumption that the only way to safely use this
attribute is if all browsers have implemented it. We don't have concurrence
from all browsers to implement this. 

According to the editor, this attribute will break if people use it without
being able to test, first. I am not making this assertion, the editor is.

If the people proposing the addition of this attribute bring it up in the HTML
WG, and all implementors of all browsers agree with its purpose, and all agree
that they will, eventually implement it, then it makes sense to consider adding
this attribute. 

But there's been no confirmation from any browser implementor about
implementing this attribute, much less all of them. And, in the editor's own
words, without this across the board agreement, the use of this attribute will
not only not work, but could very well break pages of any person using the
attribute.
