So my conclusion is that this is (mostly) premature for Python at this time. This is a slight performance enhancement of limited use that will make code at least slightly more complex in a core module that must be keep at least as rock solid as it is now. Let Google get it working on both their servers and Chrome browser. And wait for Mozilla, say, to add it to Firefox. Things might change before the first 3.4 beta, but I think 3.5 is more likely. Of course, testing will require all 4 combinations of client and server.

Agreed.

I also wonder how this relates to HTTP pipelining, a feature to improve the same multiple-requests-to-one-server situation.

Pipelining has been implemented for years both on clients and servers, yet it is still turned off per default in e.g. Firefox:

There's also HTTP 2.0 on the horizon, so it may be better to what which of those technologies actually gets enough use in practice, before adding support to the Python library.

That said, it may be useful to have a PyPI package which implements the FastOpen protocol in a separate socket implementation (which can then monkey itself into the stdlib, if the application developer wants this).
