Have you tried it?  [Insert "IT WORKS ON MY MACHINE" LOL-cat graphic here.]

As far as you know.  Look, if you think what's already there in RFC 4007 and RFC 4291 isn't clear enough, then let's see a draft to clean that up.  I'm prepared to support a reasonable effort to do that.

Really?  Having to use a zone identifier on the address literal is enough to make it too hard to type and remember?  I get that <http://127.0.0.2/> looks a little less messy than <http://[fe80::2%25lo0]/>, but it's really not *that* much worse, is it?  Outside the URI syntax, it's even easier.

I need a T-shirt that says:

            THERE'S NO PLACE LIKE ::1
  
   (except fe80::1%lo0, which is just like it)
