  Your conclusion (you disagree with my summary of your position) is
logically disconnected from your premise (I never stated that TLS-SRP

  I think you are mistaken. No one is proposing that we lose the benefits
or security proofs behind deployed and implemented security protocols.
This is not a zero sum game.
