Look, we've had this debate time and time again and its always the people
with vested interests that are against TLS.  I have yet to hear from a
single person that is against TLS who isn't either a hacker, a government
agent, or a seller of software which relies on unsecured traffic.  Not one.
 Actually, the hackers don't care that much.

I do hear what you're writing, that you think use of more TLS will somehow
cripple existing TLS, but you're ignoring that it is hackable now...  Our
use of it doesn't change that.  Despite shortcomings, we do need to raise
the bar -  there is real, documented evidence of that.  And TLS will evolve
too, and we (http) will evolve with it.

Upwards and onwards!
