Vintage kept its restricted list, because some people wanted to play with powerful cards (and also because Type 1.5, aka legacy had started to take root, which, at the time, was just vintage with the restricted list renamed "banned list"), but in standard, you already couldn't play with all your cards, so there really wasn't any good reason to keep a restricted list
