title: Are eot, ttf, and svg still necessary in the font-face declaration?
body: <p>Up until now, I've used Paul Irish's <a href="http://www.paulirish.com/2009/bulletproof-font-face-implementation-syntax/" rel="noreferrer">bulletproof font-face syntax</a></p>
  
  <p>But I was just looking at support for .woff and .woff2 files on <a href="http://caniuse.com/#feat=woff" rel="noreferrer">caniuse</a> and it says woff is supported in IE9+. Most articles on this topic are from around 2009, which at the time of this writing was a full 7 years ago. Do we really need to keep declaring ttf, otf, eot, and svg when woff now enjoys such wide support? </p>
