I don't know if the info reader ever did anything with this. I checked the source code for Texinfo 4.13 and in the "info_indices_of_file_buffer" function, it still checks if the string "Index" occurs in the name of the node. The downside of using this to find index nodes is that it would require scanning every node in the file instead of just looking at the nodes listed in the tag table. It seems not to be much of a problem in practice.
