By "highlight", do you mean the special face we use there?  If so,
that's not highlighting.

I believe this was discussed recently.  But it's a different issue;
the Info manuals provide cross-references where the author thought
they are needed.

How is this related to the issue at hand?

We could discuss whether the face alone is enough in Info.  My
personal opinion is that it isn't enough: the face we use there
doesn't guarantee any highlighting, because the user could customize
the face to be anything but.

I don't think I agree, but maybe someone else will have an opinion?

And what about Help buffers?
