This post describes the case of almost any extension or updates to TLS. If one wants to inter-operate with every server on the internet he has to support a fallback mode without any extensions and talk the 16-year old SSL 3.0. Browsers could mitigate by showing an informational message though, that either the connection is not optimal on this server (for false start), or notify it uses a protocol with known weaknesses (i.e. SSL 3.0). No browser does that, and as a result, the owners of broken servers have no incentive to change.
