Referer checking is pretty hard to deploy. I don't think it's viable as a
mass-market solution. We're trying to make Web fonts easier to deploy than
EOT, not harder.

Actually, from a very pragmatic point of view, the support for

EOT has gratuitous complexity, like pointless checksumming against
rootstring manipulation. Plus there is the possibility of rootstrings being
present and the fact that some browsers will process them and others won't,
which will always be hurting interop. We can do better.

And, if a browser encounters a website using EOT version 2.1 or later,

That's still unnecessary complexity.
