The above is a good argument why doing the right thing now is more
important than getting backward compatibility perfect: we're still
early enough in the IDNA support cycle that large numbers of clients
don't do it, or do it imperfectly.  It will be way harder to fix
things later.  Therefore, getting it right once even if it is more
painful in the short term will pay off more handsomely in the longer

(It also strikes me that this ground is well-tilled, but maybe not
everyone who is paying attention now was paying attention the last
time around.)
