With AES widely available in free code, adding export controls today wouldn't seem to do much damage to symmetric crypto at least. Maybe post-quantum schemes could be affected, but it's only a question of time until people agree on a standard, and if that one gets exported and doesn't get broken, controlling crypto exports won't prevent anyone from using secure ciphers.
