I agree, but it has to be weighted against how often that's needed and what the cost of specifying and implementing are. Browser vendors don't seem too keep on this cost / benefit ratio at the moment.

I'm not sure I follow. Look at this example:

http://jsbin.com/favini/edit?html,css,output <http://jsbin.com/favini/edit?html,css,output>

You can do the equivalent of your

With just as few properties (fewer if you count display), and without invoking calc.

This isn't to say that box-sizing:margin-box is wrong, but it isn't urgently needed.
