This makes me sad.

I would have SIGNIFICANTLY preferred if temporary/ephemeral RSA
had been retained and the restriction to the RSA_EXPORT ciphersuites
had been removed instead.

As I had previously explained, the use of temporary/ephemeral RSA
with same-strength keys as the server's certificate would make
key-stealing of the servers' key much less useful for passive
attacks.
