Well, some people support both, but other people support just the reserve requirements.
Full reserve banking has rarely been implemented, so I doubt it is a return to a golden age where they were common. It also can be argued that the ability to create money induces wealth appropriation by the rich (see the paper I linked). Finally, many Chicago economists (and apparently some economists in the IMF too) believe full reserve banking is a worthwhile idea, so it cannot be that far from the mainstream.
