Actually IDNA2008 doesn't provide any standard mapping form, so users expecting reasonable IDNA2003 mappings will break quite often :(  Fortunately UTS#46 helps with that.

Primarily we hear when they're annoyed :)  When something "breaks" we are bound to have tons of feedback about the change.  Obviously we want to "do the right thing."  Getting there from the current installed base is sometimes tricky.
