I still have hope we can rescue the extension.  The use-case I have seen
is that server cert chains and list of trusted CAs can easily make a TLS
30-40kb large.  Caching would reduce this.

However, TLS session resume also solves this problem, and it is
relatively easy to implement in most libraries.
