You'll have to use their "new" version of a URL.

Sounds like Google is becoming a bully ;p. They shouldn't reset standards of World Wide Web.

It seems to me that what they want to get rid of is URL display in the omnibar as identification of the current page, preferring to relegate it got being a machine locator and not the primary exposed content identifier.

I'd imagine you'd still keep a UI for extracting a sharing the locator unless whatever friendly identifier was adopted also came with a reliable and widely supported way of recovering the corresponding URL.
