Users of Info has no need for such a command. First, in Info you don't usually visit the Index node; instead, you use the Info-index command to jump to an indexed place. And if you do need for some reason to look inside the Index, the usual search commands (C-s etc.) will quickly get you to the right place. PDF readers also have search commands, so I'm not sure what exactly is missing here.
