It's a lot older than Texinfo 5.0, as far as i gather.
It's present in one of the initial commits in the git history, in commit
16440098c62 (2002-08-25), in file texinfo/makeinfo/node.c:
/* The order is: nodename, nextnode, prevnode, upnode.
If all of the NEXT, PREV, and UP fields are empty, they are defaulted.
You must follow a node command which has those fields defaulted
with a sectioning command (e.g. @chapter) giving the "level" of that node.
It is an error not to do so.
The defaults come from the menu in this node's parent. */

This comment is unchanged from Texinfo 3.1, from 1993. (I haven't
tried building any of these old releases to check how automatic node
pointers work, though.)
I don't know if many of the releases in the Texinfo 3.* series are
still available anywhere. On ftp.gnu.org there is only 3.0, 3.1, 3.9
and 3.12 (I remember some of those were not original tar distributions
and were sources I salvaged from other places on the Internet.)
