It's a very interesting feature. What would be the best fit for it?
Home address would be too complex with too much variations, same thing for gender or title. Login/password would be better handled by a token cookie...
It seems to be best used for email or phone number fields, or other very standardized data only.
Addendum: the example given in the post would be bad, as for most credit card forms you would want a control code input, and generaly wouldn't want to encourage sensitive data to be autocompleted.
