I don't see anything in Amazon, for instance, being a link but unsafe. I 
do see lots of buttons that may initiate something safe, but links being 
safe is the thing which is important, not buttons being unsafe.

How can it be not on purpose. It's not trivial to hide a POST behind a 
text link. Let's educate web designers not to do that.

More stuff that enables web pages to initiate a POST when it looks like 
simple link navigation.
