Why is it important? The main thing that matters is than only one definition exists for an item, irrespective of how often it is used.
A few months ago I looked a TagInfo for tags that people are using but have no Wiki entry. Once you get closer to like 100 uses and below you find a lot of tags that probably only have one definition, but aren't really that great. Like wrong key, bad/not english, used by just a few mappers, maybe local etc.
