I think that it's definitely still pretty useful as it is - it's giving more useful information than the simple "this ship" link for IMO ships, especially as you say, Ken, showing wrong or outdated categories (very useful as we work through fishing vessels, in particular - with excellent help from a couple of members in particular I am pleased to say). For Admin doing corrections, working with this in conjunction with the Correction Tool's searching by name/part-of-name takes much of the tedium out of our endeavours.
My assumption, from the design of the page, is that it was precisely intended to show the individual ship analysed by Category, Member and Name. If this last worked, it would make spotting the mistyped or just varied name (eg I or 1) so easy to spot.
