New Adsense Login System.

is it for all?

I just wanted to know for informative purpose:

Are users still using the OLD email (username) based login system for Adsense, or it was made compulsory by google to use ONLY single Google A/C across all Google services. in short are users using both the OLD login and new login or just the new one.

I am able to login by both my present email (google account) and also past email.

I haven't yet been asked to upgrade (though I have for AdWords).
