Comment (by cypherpunks):

 >  Why is this security hole still present?

 Any PoC it was used for False Start protocol?

 {{{
    Clients MUST NOT use the False Start protocol modification in a
    handshake unless the cipher suite uses a key exchange method that has
    been whitelisted for this use.
 }}}
 {{{
    Implementations may have their own whitelists of key exchange methods
    and client certificate types
 }}}

 {{{
 ECDHE is allowed, but DHE (and RSA) are not.
