Ehhh... I can see the argument, but it seems to me to be precisely on par with that you can put arbitrary text inside a <a> tag. Which means a link which looks like http://www.amazon.com might not actually go there. Some people confuse this, some don't, but many have been 'trained' by spam to check the address on mouse-over.

At least modern browsers don't let the page to cloak the address by setting window.status anymore. IIRC that was quite popular in 1990s.
