Google Page Creator removes new feature

On September 21st, Google introduced a new feature on Google Pages that let you "create a site with a different address" -- but it has recently been removed.

As you can see in these screen shots, the link used to appear just below the "Page Manager" link.

Before: 

After:

Even the help page still has information about the missing feature.

2. How do I create a new site?

Select the "Create a site with a different address" link that appears near the top of the Page Manager. 

I don't know the reason behind its removal, but it sure didn't stick around very long.  Maybe their experiment failed -- or are they just making room for another?
