+1, with caveats (clearly)

I like them :)   But that's digressing I think.

Obviously I agree and am in favor of #3.  Sorry for my part in randomizing :)  Of course it's up to the browsers, etc. about when they want to do what, but as far as the other standards go, they should point at IDNA2008, and I would prefer other standards also point to TR46, even if they qualify the reference.

Everyone worked really hard on IDNA2008.  It's not perfect, but it's the consensus that the experts arrived at.  "Other" standards should be pointing at that effort, not picking some other course or sticking with 2003.
