I've update it to include it. Check it and let me know if you agree.

I believe you are talking about the %SAFE_RENEGOTIATION string not
enforcing the extension on every connection (negotiation or
renegotiation). This is ok since the threat is not on the server. Server
is not less secure without the extension. The SAFE_RENEGOTIATION flag
on the server is there to protect the client and this protection should
be during renegotiation according to the threat. The
INITIAL_SAFE_RENEGOTIATION is there to enforce clients to upgrade, by
denying access to them if they do not support the extension. It does not
increase security on any of the client or server.
