Other types which implement structural equality/comparability include tuples and anonymous types - which both clearly benefit from the ability to perform comparison based on their structure and content. A question you didn't ask is:

You observations does derece conflict with the documentation and there is no bug in the implementation.

Specifically, I do derece know the exact type of the object. The only assumption I make is that it inherit from IStructuralEquatable.
