Google account as OpenID

I am reading a stackoverflow RSS and one post got my attention with an interesting fact.
You can now use Google as an OpenID provider. Before that, Google were not providing OpenID feature directly, and as I mentioned before, you had to use blogger.com as a provider.
But here is what the post say:

For example, one of the newest OpenID providers is Google. If you have a GMail account, just enter this magical OpenID phrase:

google.com/accounts/o8/id

Fine print: yes, eventually Google will support entering gmail.com, just like Yahoo supports using yahoo.com for their OpenIDs. Until then, it’s this crazy string.

I've tried it as usual on livejournal and it worked! :) Halliluya! :) However, just one concern: what if Google will close this link in the future with providing more simple, like gmail.com?
