While I haven’t been able to test them all, mostly because I don’t know many, I’ve noticed that ambiguous tags no longer notify you of the fact that they’re ambiguous when you include them in a search (the little box at the top with "This tag is potentially ambiguous blahblahblah"). Tags like sakura, archer, knight, ronin and so on for example.
Of course, anyone can still look up all variants by typing the tag *like this* so it’s not a functionality issue, but doesn’t the absence of the warning make classifying a tag as ambiguous kind of… well, pointless?
