The lack of real value in TLSv1.1, the additional weaknesses of TLSv1.2,
and the interoperability problem of sending ClientHello.client_version
with a value higher than { 0x03, 0x01 }.

Did any browser try to ship TLSv1.1 or TLSv1.2 without including
a reconnect fallback facility?  How many browsers did reconnect fallbacks
prior to using TLSv1.1 or TLSv1.2?

The reasons for TLSv1.1/TLSv1.2 not deploying is not very much different
from why IPv6 is not deploying.  Huge complexity and negligible value.
