if a surfer right-clicks on a url on a page and pastes it into their browser, depending on a few different factors, they can get the entified or deentified link.

Since there is some inconsistency there, or, when used in trade scripts, etc, it just seems to me that better safe than sorry would be the rule of thumb. Especially since IE 5.5 also seems to exhibit the behavior even on clicked links.
