Yes, but that's not the same thing.  There are many completions
of `i buffer TAB', and there's no indication that the `buffers'
one will take you to a definition.  (An index entry like `buffer,
definition' would make that clear.)

In any case, the enhancement request explicitly acknowledged
that Emacs already provides ways to get to glossary items.
The request is to optionally highlight occurrences of the
term, so that you can notice that it's a glossary term and immediately jump to 
it from any context that uses it.
