The intent of the "offending"
statement in 11.1 was to have a strong player with a new method forcing
everybody into it by not offering anything else.
I guess the phrasing was bad.  Simply
removing None will not do it since None may still remain a valid option
if both parties agree:

I would suggest the new phrasing to
be:

Private or public extension algorithms
MAY also be negotiated for authentication methods. Whenever a private or
public extension algorithm is offered, at least one of the authentication
methods defined in this document MUST also be offered as an option.
