I tend to fail these uniqueness tests pretty catastrophically, and I hadn't heard of Canvas Defender. But solutions like that seem a bit heavyweight to me (and more likely to affect the UX negatively). Is this really the only way to get around this problem?

Yeah, I do too, my useragent string is somehow almost completely unique. I try using a more "common" one and suddenly everything locks me out.
Canvas Defender only adds noise on hidden canvases, ones that are obviously being used for fingerprinting.
But yeah there's no perfect solution. If you simply block canvas rendering, like some plugins do, that is a 100% identifiable signal. So the best you can do is make the fingerprinting "unsure" that that is you, by having the fingerprint be different every time.
