Personally, I'm not trying to model all of human knowledge in my Org
files! I suppose if you were an academic researcher it might be a bigger
issue, but I count 71 different tags in my agenda files, and I don't
feel overwhelmed. You can get a bit of tag hierarchy with tag groups,
but admittedly only a bit.

To my knowledge, no one's implemented a reverse link lookup, but it
should certainly be possible. Using the <<<foo>>> link notation as a
tag, however, would probably end up being more work (and more confusing)
than it's worth.
