I've actually used urls with a path for the origin; specifically when I 
wanted to pass in "the origin of this page".  In particular, I passed in 

I'm fine with removing the ability to pass in a path _if_ we create a 
simple way for scripts to get origins from pages which can then be 
passed for this argument.  The alternative is that scripts will be 
parsing location.href themselves to extract the thing to pass as the 
origin string, which is just asking for security fail in my experience.
